Question

why do HCl , HNO3 ,etc...,show acidic characters in aqueous solutions while solution of compounds like alchohal and glucose do not show acidic character

Answer 1

When HCl or HNO3 are mixed with water then they dissolve in water to form H+ or H3O+ ions which shows their acidic character. For example just see the following reactions

When alcohols and glucose are mixed with water then they do not dissolve to form ions. Hence they do not show acidic character.

Answer 2

Answer:

Acids in aqueous solution:

-The acids are molecules which are capable of producing ions (protons) when dissolved in water. This protons gives the acidic nature to the aqueous solution.

-When inorganic acids like HCl,  reacts with water to produce hydrogen ions in aqueous solution whereas in organic compounds like glucose and alcohol reacts with water to form immiscible solution.

-Though the hydrogen atoms are present in the organic compounds, this atoms do not part from the carbon atoms easily. But that is not the case in inorganic compounds.
