Preparation of sodium bicarbonate

Preparation of sodium bicarbonate

The Solvay process depends on the fact that of all the possible combinations of ions present in the aqueous reaction mixture (NH4+, Na+, Cl, HCO3) sodium bicarbonate is the least soluble and hence precipitates out first under the proper concentration conditions. 60g of powdered sodium chloride are added to 180g of a 10% aqueous solution of ammonia and the mixture is allowed to stand, with occasional swirling, until al most all the salt has dissolved. The filtered solution is placed in a 1-liter flask fitted with a gas delivery tube leading al most to the bottom of the vessel and an exit tube of narrowbore glass (3mm inner diameter). A steady stream of carbon dioxide (about 3 bubbles/sec) is led into the flask, which is swirled from time to time. After some time, when the saturation point of sodium bicarbonate has been exceeded, the product suddenly precipitates. The carbonation is continued for four hours, the mixture is then cooled in running water and filtered by suction. The product is pressed down well, washed with 25ml of ice water and dried in air. Yield 55-58g.
