Choosing only the substances from the list given below, write the equations for the reactions which you would use in the laboratory to obtain:
Dilute sulfuric acid, copper, iron, sodium, zinc, copper carbonate, sodium carbonate
(c) Iron $(III)$ sulfate

Solution

Material used:
Dilute Sulfuric acid $(H_{2} {SO}_{4})$
Iron $(Fe)$
Reaction summary:
This reaction can be carried out using dilute acid and active metal. The salt so formed then passes into the solution and can be obtained by crystallization.
When dilute Sulfuric acid $(H_{2} {SO}_{4})$ reacts with Iron $(Fe)$ , it will form Iron sulfate $({Fe}_{2} {({SO}_{4})}_{3})$ and Hydrogen gas is liberated $(H_{2})$
Balanced chemical equation:
$2 Fe (s) + 3 H_{2} {SO}_{4} (dil .) \to {Fe}_{2} {({SO}_{4})}_{3} (aq) + 3 H_{2} ↑$
