Explanation:
When we added Zn in H2SO4 we get hydrogen gas + Zinc salt.
Zn. + H² SO⁴ _____ ZnSO⁴ + H²
When Lead added to H² SO⁴ it gives hydrogen gas + lead salt.
Pb + H² SO⁴ ---------- PbSO⁴ + H²
when sodium sulphate is added to sulphuric acid there will be no reaction takes place.
When sodium carbonate is added to H² SO⁴ it forms carbon dioxide and water and sodium salt.
Na2CO3 + H² SO⁴ ------- Na2SO4 + CO2 + H2O
when we added calcium carbonate to H² SO⁴ we get calcium salt with carbon dioxide + water.
CaCO3 +H² SO⁴ ----- CaSO4 + CO2 +H2O
