Name the gas evolved when dilute sulphuric acid acts on sodium carbonate.Write the chemical equation for the reaction involved.
Reaction of acids with metal carbonates An acid reacts with metal carbonate to give salt, water H2O, and carbon dioxide CO2 as the product. Brisk effervescence is observed, confirming the released gas to be carbon dioxide. Chemical Reaction Sodium carbonate Na2CO3 reacts with an acid, i.e., sulphuric acid H2SO4 to give salt along with carbon dioxide and water. Brisk effervescence is observed, indicating the presence of carbon dioxide gas. The reaction is as follows, Na 2 CO 3 ( s ) + H 2 SO 4 ( aq ) → Na 2 SO 4 ( aq ) + CO 2 ( g ) + H 2 O ( l )
