2 Which gas is evolved when sodium hydrogen carbonate (NaHCO3) is added to acetic acid? |
|
Answer» When sodium hydrogen carbonate is added to acetic acid, carbon dioxide (CO2) gas is evolved. NaHCO3+ CH3COOH CH3COONa+ H2O + CO2 (Sodium hydrogen carbonate + Acetic acid = Sodium acetate + water + carbon dioxide) Carbon dioxide supports all the above three properties. CO2turns lime water milky, it is a non-supporter of combustion and is absorbed by strong alkalis such as NaOH. |
