Question

Zinc is treated with conc. Sulphuric acid

Answer 1

Reaction of Zn with H2SO4 depends on concentration of acid.

For dilute acid, zinc sulphate and hydrogen gas at produced.

Zn + H2 SO4 → ZnSO4 + H2

For concentrated sulphuric acid, zinc sulphate , Sulphur dioxide and water are produced.

Zn + conc. 2 H2SO4→ ZnSO4 + SO2 + 2 H2O

** Concentrated sulphuric acid on reaction with metals produce salt, water and the product of reduction of sulphur.

Hope it may help.

Thank you :)

Answer 2

It will form Zinc Sulphate i.e. ZnSO4....
