Question

Name the salts which are formed when Zn metal reacts with following acids. a. nitric acid b. phosphoric acid c. acetic acid

Answer 1

Answer. When Zn metal reacts with nitric acid it will form zinc nitrate
 
    4HNO3(aq) + Zn(s) ——— > Zn(NO3)2(aq) + 2NO2 (g) + 2NO2 (g)

When it reacts with phosphoric acid it will form zinc phosphate

   2H3 PO4(aq) + 3Zn(s)    —————>  Zn3 (PO4) 2(aq) + 3H2(g)

When it reacts with acetic acid it will form zinc acetate
  2CH3COOH(aq) + Zn(s)            Zn(CH3COO)2(aq) + 2H2(aq)
