Preparation of sodium hydroxide (caustic soda)

Preparation of sodium hydroxide (caustic soda)

53 g of anhydrous sodium carbonate are dissolved in 300 ml of water. Separately a solution of 50 g of  calcium hydroxide in 300 ml of water is prepared. The sodium carbonate solution is brought to boiling and to this solution the milk of lime is slowly poured with constant stirring. The reaction mixture is boiled 15 minutes and then filtered, using a suction bottle. In order to obtained crystalline sodium hydroxide, the filtrate is evaporated in the inert atmosphere (nitrogen, argon) or preferably in the vacuum.
