Question

A highly reactive metal is added to a dilute mineral acid water is formed instead of hydrogen gas. what is the mineral acid.
Please please please help me.

Answer 1

When metals( Cu, Na, Zn) react with mineral acids like dil HCL and H2SO4, hydrogen gas is evolved.

Nitric acid is an acid that decomposes very quickly.

When metals react with mineral acids except nitric acid, the respective salt and H2 gas is evolved.

How do you confirm that the gas released is hydrogen?

When you introduce a burning splinter the gas will burn with a pop sound.
