Question:I got a test tomorrow, I need to know how they differ on a molecular and physical level. Thanks!
Answers:electrolytes react with water to form ions in solution, and nonelectrolytes have molecules.Electrolytes are ionic compounds and some covalent compounds like strong acids. Non electrolytes do not ionize in water. Only covalent compounds like CH4 and C6H6 can be nonelectrolytes
Question:please explain, i have a final exam tomorrow and i can't seem to understand this. can some one make it more clear for me please. god bless you.
Answers:If it's a soluble compound containing a metal...
If it's a dilute strong acid...
...then it's an electrolyte.
Question:While you're at it, is nitric acid a strong, weak or non? And ammonia?
Answers:Hydroflouric acid is a strong electrolyte because of hydrogen bonding.
I am almost positive that ammonia is a weak electrolyte.
I think Nitric acid is a nonelectolyte.
I hope this helps. Sorry if I am wrong.
Question:and potassium iodide, KI is a strong electrolyte. Give the moles of solute particles formed by each if 0.1 mol of each compound is dissolved in water. Write equations to show reasoning?
Answers:C12H22O11 does not give ions so we find out 0.1 mol when it is dissolved in water because does not dissociate
CH3COOH <> CH3COO- + H+ Ka = 1.8 x 10^-5 is a weak electrolyte so we find out a number of moles between 0.1 and 0.2 when it is dissolved in water. It is incompletely dissociated
KI >> K+ + I- is a strong electrolyte so we find out 0.2 moles when it is dissolved in water
Electrolytes :The term electrolyte is a term used when talking about solutions with water as the solvent. We demonstrate the property of being an electrolyte with an electrical conductivity tester like this. Pure water does not conduct electricity. I will put the electrodes of this apparatus into a beaker of pure water. There is no light coming from the light bulb. If I dissolve a material in this water and the light lights brightly, the dissolved material is called a strong electrolyte. As an example, here is a small amount of table salt. As I add it to the water and dissolve it, it dissolves by breaking into charged particles, the ions of sodium and chlorine, which now allow the solution to conduct electricity. So the ionic substance table salt is a strong electrolyte The term non-electrolyte refers to a substance which dissolves in water but does not allow electrical conductivity. Here is some water and some sugar. As the sugar dissolves, the light does NOT light up. So sugar is a non-electrolyte. Some acids and bases are also strong electrolytes. Here as an example is some hydrochloric acid. Only a little in the water allows the light to light up very brightly. So the acid is also a strong electrolyte and is called a strong acid. Acetic acid, on the other hand, dissolves but allows very little electricity to go through the water. See how the light bulb gives off much less light. Thus we call acetic acid a weak electrolyte and a weak acid.
Electrolytes and Non Electrolytes :Check us out at www.tutorvista.com Electrolyte: a solution that conducts electricity Acids, bases and salts in solution are all examples of electrolytes. Non-electrolyte: a solution that does not conduct electricity The positive ions found in electrolytes accept electrons and the negative ions return them to the circuit. Above: Na+1 + 1e Na 2 Cl-1 Cl2 + 2e 2. From the point of view of physical properties, what do electrolytes have in common? Non-electrolytes? Electrolytes and non electrolytes both interfere with the boiling and freezing of water. Thus they lower the freezing point of water and elevate its boiling point. 3. What chemical properties do electrolytes share? Non-electrolytes? Electrolytes react quickly because their reactions involve the simple breaking and reforming of ionic bonds. Generally non electrolytes react more slowly because their reactions involve covalent bonds, which are harder to break and reform
