In the following schematic diagram for the preparation of hydrogen gas as shown in figure, what would happen if following changes are made ?

Sodium hydroxide is taken in place of dilute sulphuric acid and the tube is heated.

Text Solution

Verified by Experts

If sodium hydroxide is taken in place of dilute sulphuric acid and the tube is heated, sodium zincate is formed along with hydrogen gas. But heating of test tube will increase the rate of formation of hydrogen gas as heating of reaction mixture increases the rate of reaction.
