Question

In a laboratory, which is the other compound that is used along with sulphuric acid to produce nitric acid?

• A. $KN{O}_3$
• B. $S{O}_2$
• C. $HCl$
• D. $N{H}_3$

Answer 1

The correct option is A $KN{O}_3$

There are two compounds that are used for the production of nitric acid in a laboratory. In a laboratory, nitric acid is formed by the reaction of potassium nitrate and sulphuric acid. The other product that is produced is called potassium bisulphate ($KHS{O}_4$). The equation for this reaction is given below.

$KN{O}_3+H_{2}S{O}_4\to KHS{O}_4+HN{O}_3$

So the other compound that is used in this reaction is potassium nitrate ($KN{O}_3$).
