Importance of pH in Everyday Life


There are various things that are required by the human beings in the day to day functioning of the human body. 
There are vital organs in the human body that carry out various important functions. 
There are enzymes and chemical substances called the hormones also present. 
The hormones are used for coordination between the various functions in the human body and for a better balancing of these chemicals the advent of pH is very important. 

There is lot of importance of pH in everyday life of an human being. This concept has to be clearly understood in order to proceed further. 
There is range of value of pH within the human body works. There are certain terms called acid indicator and base indicator. 
They have to be studied in order to understand the concept of pH. 
They are basically used to know how the water in the swimming pool is safe for us or why the food we eat everyday is not going to have an adverse effect on us. 
The value of the pH for the human body is in the range of 7 to 7.8. This range shows the importance of pH in everyday life which makes an important statement about the kind of environment we would like to be in. 

The pH of the rain water could also be measured and it is experimentally found that most of the rainfall for the first 10 -15 minutes is acidic in nature. 
If the value of the pH is found to be less than the value 5.6 then the rain is thought to be acidic. Acidic rains is highly damaging in nature. The acidic rain effect is evident for architectural marvel of the world the Taj Mahal. The main cause of this is the Mathura Oil refinery and many of the factories that has come up in the vicinity of Taj.
The air in the surrounding areas are polluted and are filled with gaseous particles responsible for such type of rain. This type of rain could cause damage to the crops as well and change the pH of crop field soil profile.

Even in our digestive system, particularly the stomach, contains digestive juices or acids that help in the process of digestion and since the process of digestion is very important one the pH plays a big role in maintaining the neutral atmosphere of the stomach.

During this process of digestion a lot of acids are also secreted in the stomach. These acids if not neurtralised on time could damage the inner linings of the stomach and food pipe as well. 

To neutralize the acids that are produced, some bases needs to be added. These bases are taken externally in the form of tablets and syrups which are basically nothing but diluted form alkaline suspension like milk of magnesia. 

So, the importance of pH in everyday life is immense. The presence of pH in mouth is also important. This pH value is roughly around 5.5. 
Once the food is taken in and pushed through food pipe there are still some particles of food remaining in the mouth cavity. 

The bacteria present in the mouth starts breaking down these food particles and while doing so produce acids which usually damage the teeth or trigger the teeth decay teeth.
The human teeth are made up of a material that is the hardest in nature, and is not corroded by any substance. But when these teeth are exposed to the acids generated by the bacteria they are prone to tooth decay. 

This can be prevented if one is a bit careful. Wash and rinse mouth thoroughly after taking food. Mouth wash could also be used. The teeth can be brushed twice a day and this helps a lot in preventing the tooth decay. 
In order to neutralise the effect of mouth cavity acid build up the tooth pastes are found to be basic in nature.

Question:Why are acid and base indicators important? How could they be used in everyday life?

Answers:They're important for giving a pretty good estimate of the pH of a solution. How can they be used in everyday life? Well people normally don't go around carrying a bunch of acid/base indicators with them. They're used more for academic purposes. I guess they could be used for things like pools and rain water...

Question:name three situations in which acid base indicators might be useful in everyday life

Answers:testing pH of blood looking at bacterial activity - when they respire they lower pH testing a water sample so fish can live happily in a lake

Question:why are school teaching it to little 8-9 year olds and younger? another problem with schools i have, is when doing "real" everyday math, we were automatically told to use a calculator. now, ppl my age and younger, generally have problems handing back chance from registers, if having to think in your head. example: if working a concession stand, and the register does no tell you what to give back. i know this does not apply to everyone but who on here has the same issues and concerns about school? just wondering. correction- instead of "chance", i meant "change" in that sentence!

Answers:Algebra is used frequently in everyday life, but we don't often think about the fact that we are using algebra. If you are trying to figure out how many packages of hot dog buns to buy for a party, you are using algebra. Planning a budget for a road trip based on gas prices and gas mileage - using algebra. As for why it's being taught as early as Kindergarten (yes, those old problems Square +1 = 2, what goes in the square? - algebra!), it's to develop algebraic thinking. Thinking about algebra means thinking in a unique way in which numbers combine not just in a forward 1+2=3 but also in a 3-2=1 or 2+1=3 way and so on. The sooner we introduce students to this form of thinking the more successful they will be with any type of logic problem presented to them, not just algebra. However, I agree with you about calculators. It is important to teach students how and when to use calculators. It is also important to teach students how to estimate so they know if they made a mistake leading to a wrong answer on a calculator. Calculators can only be as good as the people using them.

Question:need help with a chemistry project and one thing we gotta talk about is how mgcl is used relevant to our lives, like iron is used in nails or aluminium in coke cans - they are like used in everyday life so by any chance does anyone know what we use frequently that contains mgcl? thanks! xxx

Answers:Culinary use ------------------- Magnesium chloride is an important coagulant used in the preparation of tofu from soy milk. In Japan it is sold as nigari ( , derived from the Japanese word for "bitter"), a white powder produced from seawater after the sodium chloride has been removed, and the water evaporated. In China it is called "lushui" ( in Chinese). Nigari or Lushui consists mostly of magnesium chloride, with some magnesium sulfate and other trace elements. It is also an ingredient in baby formula milk. Use as an anti-icer ----------------------------- A number of state highway departments throughout the United States have decreased the use of rock salt and sand on roadways and have increased the use of liquid magnesium chloride as a de-icer or anti-icer. Magnesium chloride is much less toxic to plant life surrounding highways and airports, and is less corrosive to concrete and steel (and other iron alloys) than sodium chloride. The liquid magnesium chloride is sprayed on dry pavement (tarmac) prior to precipitation or wet pavement prior to freezing temperatures in the winter months to prevent snow and ice from adhering and bonding to the roadway. The application of anti-icers is utilized in an effort to improve highway safety. Magnesium chloride is also sold in crystal form for household and business use to de-ice sidewalks and driveways. In these applications, the compound is applied after precipitation has fallen or ice has formed, instead of previously. The use of this compound seems to show an improvement in driving conditions during and after freezing precipitation yet it seems to be negatively affecting electric utilities. Two main issues have been raised regarding the anti-icer magnesium chloride as it relates to electric utilities: contamination of insulators causing tracking and arcing across them, and corrosion of steel and aluminium poles and pole hardware.

Family, The Most Important Thing In Life :ronandlauraperkins.com 7 Steps to Building a Strong Family. 1. Strong families make it a priority to spend time together, and are committed to each other. This does not have to mean organizing great days out, but doing everyday tasks such as running errands, household chores or playing games together. Have a notice board in a prominent place in your home, with a daily REMINDER that your family comes first. This may seem crazy, but our hectic lifestyles with work and school mean we can frequently forget to take time out and work on our family relationships. 2. Ask yourself, why am I so busy? What am I doing, and is it helping to strengthen our family, or causing us to be apart more often? Is what I am doing really worth it? You may find that, when you stop and think about it, there may be activities you can cut out, or you may find ways of managing your time more effectively. 3. Some of those issues that have been important to you, on reflection, you may be able to re-prioritize. For example, household chores, like cleaning, or not allowing your kids to do 'messy' activities like painting or cooking. Being less fastidious about such issues may unlock time for being together and having fun. 4. Is your child attending lots of after-school clubs? Some parents like to feel that their child is constantly occupied and gaining new interests, and this is great, if that is what they are really doing. If a child loves doing many activities, that is good, but some children like to ...

The College Network -- The Importance of Pedagody and Andragogy :Carla A. Downing, Ph.D, Vice President of Product Development and Academic Support, discusses pedagogy and andragogy at the 16th Annual Sloan-C International Conference on Online Learning in November, 2010 in her presentation "The Importance of Pedagogy and Andragogy." Dr. Downing compares and contrasts pedagogy and andragogy, discusses how needs for structure and autonomy differ between the two and how life's experiences are incorporated into learning. She also discusses how "true learning" can be facilitated and how students can be taught how to "connect the dots" when pedagogical and andragogical practices are successfully incorporated along with adequate time for students to reflect.
