What happens when zinc granules are treated with dilute solutio of `H_(2)SO_(4), HCl, HNO_(3), NaCl` and NaOH ? Also write the chemical equations if reaction occurs.

Explanation

With dilute `H2SO_4` zinc gives zinc sulphate and hydrogen gas.

Zinc when reacts with dil. HCl, it gives zinc chloride and hydrogen gas.
`Zn_((s))+2HCl_((aq))tounderset("zinc chloride")(ZnCl_(2(aq)))+H_(2(g))`
Zinc does not react with NaCl solution.
Zn + `NaCl_(aq) to` No reaction
Zinc reacts with hot NaOH solution to form sodium zincate and hydrogen gas.
