Procedure
13.4 grams (0.24 Mole) of calcium oxide and 30 grams (0.16 Mole) of citric acid were placed into a beaker provided with a reflux condenser. 80 ml ethanol was added and the mixture was stirred and boiled at atmospheric pressure for 2 hours. The reaction mixture was cooled and thereafter filtered yielding 39 grams of calcium citrate having the physical characteristic of a fine white powder.
