(ii) Used in aerated or fizzy drinks e.g. mineral water.
(iii) Used in refrigeration – solid carbon dioxide or ‘dry ice’ is used as a refrigerant. It is used for keeping ice- cream cold and top deep freeze food.
(iv) Baking – Baking powders consist of a mixture of 2,3 – dihydroxybutanedioic acid and sodium hydrogen carbonate. In presence of water they react to form carbon dioxide, which cause the dough to rise.
(vi) Solvay process – in the manufacture of sodium carbonate.
