I think it is a nitric acid

Dominique Bean · Answer 2

a) B is an acid

b) carbon dioxide

c) it is salt of the acid

Explanation:

a) B dissolves to produce an acid. An acid, according to the Bronsted-Lowry theory, dissolves in an solution to give an acid solution of a pH less than 7 on a pH scale.

b) carbonates gives a gaseous effervescence. The gas given off is carbon dioxide

c) The solution is a salt of an acid. This is in an aqueous solution.
