Question

What are the gas liberated when dilute hydrochloric acid reacts with a) zinc b) zinc carbonate suggest the experiment to identify these gases. Dey hydrogen chloride gas does not exhibit acidic properly. why

Answer 1

Answer:

Explanation:

When dilute hydrochloric acid reacts with zinc, it liberates hydrogen gas.

Experiment:  When a burning splinter is brought near hydrogen gas, it puts off   the burning splinter with a pop sound.

When  dilute hydrochlolric acid reacts with zinc carbonate, it liberates   carbon dioxide gas.

Experiment: When carbon dioxide is passed through lime water it turns the lime water milky.

Dry hydrogen chloride gas does not show acidic properties because, until and unless HCl comes in contact with the moisture it doesn't produce Hydrogen ions.

An element shows acidic properties only when it produces hydrogen ions.

Hope the answer helps you!
