Question

What happens when zinc granules are treated with dilute solution of h2so4,hcl hno3 nacl and also write the chemical equation involved if reaction occur

Answer 1

NaCl and NaOH do not react with zinc granules.

HCl , H2SO4 and HNO3 are acids and they react with zinc to liberate hydrogen gas.

2HCl + Zn --> ZnCl2 + H2 (gas)

H2SO4 + Zn --> ZnSO4 + H2 (gas)

2HNO3 + Zn --> Zn(NO3)2 + H2 (gas)
