Question

Q.19. What happens when zinc granules are treated with dilute solution of $H_{2}S{O}_4,HCl,HN{O}_3,NaClandNaOH$? Also write the chemical equation if occurs.

Answer 1

Dear Student

Zn+H2SO4 →​ ZnSO4+​H2(g)

Zn+2HCl → ZnCl2+H2(g)

3Zn+8HNO3 ​→ 3Zn(NO3)2+2NO+4H2O

Zn+Nacl ​→ no reaction (beacuse very reactive to be replaced by zinc in a compound)

ZnO+2NaOH ​→ Na2ZnO2+H2O
