Answer»

[A] Lead (II) oxide, when heated with powdered coke, reduced to metallic lead and carbon monoxide is formed.

PbO + C ⟶ Pb + CO

[B] Lead (II) oxide, when dissolved in the dilute nitric acid, lead nitrate is formed.

PbO + 2HNO₃→ Pb(NO₃)₂ (Lead nitrate) + H₂O

[C] Lead (U) nitrate is dissolved in water and then sodium hydroxide solution is added, a white precipitate of lead hydroxide is obtained.

Pb(NO₃)₂ + 2NaOH→ Pb(OH)₂ + 2NaNO₃

[D] Lead (II) nitrate is dissolved in water and then concentrated solution of sodium carbonate is added, a white precipitate of lead (Il) carbonate is obtained.

Pb(NO₃)₂ + Na₂CO₃ → PbCO₃ + 2NaNO₃
