Give equation...

Question

Give equations to prepare the following as directed:
(a) MgCO₃ from MgCl₂
(b) PbCO₃ from Pb(NO₃)₂
(c) NaHCO₃ from Na₂CO₃

Open in App

Solution

(a) Magnesium carbonate is prepared by treating magnesium chloride with sodium hydrogencarbonate.

MgCl₂+ NaHCO₃ → MgCO₃ + 2NaCl + H₂O + CO₂

(b) Lead carbonate is prepared by double displacement reaction between lead nitrate and potassium carbonate.

Pb(NO₃)₂ + K₂CO₃ → PbCO₃ + 2KNO₃

(c) Sodium bicarbonate is prepared by treating solution of sodium carbonate in water with carbon dioxide.

Na₂CO₃ + CO₂ + H₂O → 2NaHCO₃
