Question

Why do HCl, HNO3, etc., show acidic characters in aqueous solutions while solutions of compounds like alcohol and glucose do not show acidic character?​

Answer 1

$\huge \sf {\orange {\underline {\pink{\underline{Answer :-}}}}}$

An acid is a substance, which dissociates on dissolving in water to produce hydrogen ions [H+(aq) ions]. The acids like HCl, H2SO4, HNO3 and CH3COOH, etc., show acidic character because they dissociate in aqueous solutions to produce hydrogen ions, H+(aq) ions.

The compounds such as glucose and alcohol also contain hydrogen but they do not show acidic character. The aqueous solutions of glucose and alcohol do not show acidic character because the hydrogen in them does not separate out as hydrogen ions [H+ (aq) ions] on dissolving in water.

Answer 2

Answer:

HCl and and HNO3 show acidic behaviour in aq solution as they dissosciate in water to produce Hydrogen ions while solution of glucose and alcohol do not form ions in water
