Question

How will you test for the gas which is liberated when hydrochloric acid reacts with an active metal?

September 7, 2024

Answer

When an active metal like Zn reacts with HCl , the gas produced burns with a pop sound which indicates that it is hydrogen gas.

Zn(s) + 2HCl(aq) → ZnCl₂(s) + H₂(g)
