Question

Give the names and formulae of two strong acids and two weak acids

Answer 1

Strong Acids 1) Hydrochloric acid Chemical formula: HCl 2) Sulphuric acid Chemical formula: H2SO4 Weak acids 1) Acetic acid Chemical formula: CH3COOH 2) Carbonic Acid Chemical formula: H2CO3

Answer 2

Answer:

Strong acid: Nitric acid and hydrochloric acid.

Weak acid: Acetic acid and formic acid.

Explanation:

The strong acids get completely dissociated into stable ions which produces protons on dissociation. The acid dissociation is completed only if the acid's concentration is very high.

$H A+S \rightleftharpoons S H^{+}+A^{-}$

The weak acids cannot be completely dissociated. Thus, on dissociation, they form ions and by the end of the process, they combine with other ions to form product.

$H A \rightleftharpoons H^{+}+A^{-}$
