Gravimetric analysis is used to determine the amount of a substance in a sample by measuring the mass of a solid product or precipitate obtained by reaction of the substance with a precipitating agent. In this investigation, calcium is determined by precipitation of calcium carbonate upon addition of sodium carbonate to a solution of the sample.

It is obtained commercially by the electrolysis of dry molten sodium chloride. The liquid metal is used as a heat exchanger in certain nuclear reactors, and as a reagent in the chemicals industry. Sodium salts such as common salt (sodium chloride) and washing soda (sodium carbonate) are more important than the metal itself.

If you have too much sodium in your body, you might get very thirsty and urinate more to get rid of the excess. But sometimes your kidneys can't eliminate all of the excess. When this happens, your blood volume can increase (because sodium holds in water), which in turn can make your heart pump harder, which increases blood pressure.

Sodium and its close periodic table neighbor potassium are solids at room temperature. Their alloys however are not. NaK alloys containing 10 to 60 percent of sodium by weight are liquids at room temperature. The commercially available 78% K, 22% Na alloy stays liquid at temperatures as low as -12.6 oC (9.3 oF).
