Question
What product is obtained by passing excess carbon dioxide gas through an aqueous solution of sodium carbonate? What is the solubility of the product obtained in water? Write the equation for the reaction.

Answer

When excess of carbon dioxide gas is passed through an aqueous solution of sodium carbonate then sodium hydrogencarbonate (NaHCO3) is obtained.
Sodium hydrogencarbonate is slightly soluble in water.
$Na _2 CO _3( aq )+ H _2 O ( l )+ CO _2(g) \rightarrow 2 NaHCO _3( aq )$
