Question

1. Give an example of a monoprotic acid, a diprotic acid, and a triprotic acid.
2. Give an example of a strong acid and an example of a weak acid.
3. Calculate the concentration (in molarity) of an NaOH solution if 2

Answer 1

monoprotic acid = HCl, HNO₃ , CH₃COOH, HCOOH, etc , whcih has only 1 H⁺ to give

diprotic acid = H₂SO₄ , H₂CO₃ , (COOH)₂ which are able to give 2 protons

triprotic acid = H₃PO₄ , citric acid

strong acid = all the proton donors which dissociates completely in water and has low pKa are strong acids.

HCl, HNO₃ ,H₂SO₄

weak acid = all the proton donors which doesn't dissociate completely in water and has higher pKa are weak acids.

CH₃COOH, HCOOH,(COOH)_{2 .}

please leave full question in the comment i will answer as reply.
