Question

· An acid which gives only one type of salt when it reacts with a metal​

Answer 1

Answer:

Many, but not all, metals react with acids. Hydrogen gas forms as the metals react with the acid to form salts. This class experiment is often used in the introductory study of acids to establish that this behaviour is a characteristic property.

Answer 2

Answer:

Hydrogen gas(H2)

Explanation:

Dilute acids (except dilute nitric acid) on reaction with active metals produce a colourless and odourless gas which burns with a popping sound i.e, hydrogen gas.
