Question:A conductivity test of a dilute solution of nitrous acid has very low electrical conductivity ( the bulb on the tester glows dimly) and the pH is measured to be about 4. The same concentration of a nitric acid solution makes the conductivity testers bulb glow brightly and has a pH of less then 1. Explain the difference between those two acids.

Answers:Nitrous acid is a weak acid, because it has very low ionisation enthalpy.so it show ph-4. While nitric acid is a stronger acid, which fully ionise in water to produce more n more H+ ions, as a result the bulb glows more brightly. Hence, it has ph-1(highly acidic).

Question:

Answers:they do not have the hydrogen bonding between molecules that carboxylic acids have because of their very poistive hydrogen in the carboxyl group

Question:2 Major differences between acids and bases (biology)

Answers:Acids are H+ donors and Bases are H+ acceptors in chemical processes. Example: HCl gives H+ in the solvent water to become H+ and Cl- and is an acid. This is only one of several definitions of acids and bases but in my opinion the easiest to understand. Also, acids have a pH below 7 and bases have a pH above 7. The pH means the molar concentration of [H+] ions, 1 pH meaning 1 * 10 ^ -1 moles of [H+] ions per liter and 2 pH meaning 1 * 10 ^ -2 moles per liter. So, each 1 decrease on the pH scale means 10 times more [H+] ions and each 1 increase means 10 times less [H+] ions. Glad to help.

Question:i know acid means sour or something but what is the difference between acid and base? n what are 5 examples of acid and base

Answers:acids a proton donors, bases are proton acceptors examples of acids: hydrochloric acid HCl hydrofluoric acid HF carbonic acid H2CO3 nitric acid HNO3 sulphuric acid H2SO4 examples of bases: sodium hydroxide NaOH lithium hydroxide LiOH barium hydroxide Ba(OH)2 potassium hydroxide KOH calcium hydroxide Ca(OH)2
