Question

(a) Write the balanced chemical equations for the preparation of following salts:
(1) A soluble sulphate (by the action of an acid on a metal).
(ii) A soluble sulphate (by the action of an acid on an insoluble metal oxide).
(iii)An insoluble sulphate (by the action of an acid on another salt).
​

Answer 1

Answer:

i) Zn + H2So4--> ZnSo4 +H2

ii) Al2O3+6HCL---->AlCl3+H2O

Answer 2

Answer:

(i)Zn + H2SO4 ( very dil.) = ZnSO4 + H2

(ii) PbO + H2SO4 = PbSO4 + H2O

(iii) AgNO3+H2SO4 =AgSO4 +HNO3

hope it helps
