Question Choosing only substances from the list given in the box below, write equations for the reactions which you would use in the laboratory to obtain:
(a) Sodium sulphate
(b) Copper sulphate
(c) Iron (II) sulphate
(d) Zinc carbonate
| Dilute sulphuric acid | Copper | Copper carbonate |
| Iron | Sodium carbonate | |
| Sodium | ||
| Zinc |
a. Na2CO3 + H2SO4 (dil.) ⟶ Na2SO4 + H2O + CO2↑
b. CuCO3 + H2SO4 (dil.) ⟶ CuSO4 + H2O + CO2↑
c. Fe + H2SO4 (dil.) ⟶ FeSO4 + H2↑
d. Zn + H2SO4 (dil.) ⟶ ZnSO4 + H2↑
ZnSO4 + Na2CO3 ⟶ ZnCO3 + Na2SO4
