A : CO_2 is a Lewis acid. R : H_2SO_4 is Arrhenius acid as well as Bronsted acid.

The oxidation number of sulphur in sulphuric acid H_2SO_4 is

Find oxidation state of sulphur in sulphuric acid (H_2SO_4) .

On heating oxalic acid with H_2SO_4 , we get

Oxalic acid reacts with con. H_2SO_4 to produce

The reason why conc. H_2SO_4 is used extensively to prepare other acids is that conc. H_2SO_4 is

Why is it necessary to test for the acid radicals first with dil. H_(2)SO_(4) and then with conc. H_(2)SO_(4) ?
