Question

10. In the following diagram, what would happen if some amount of sodium hydroxide is taken in place of sulphuric acid and the test tube is heated ​

Answer 1

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.
