      In this experiment an accurately massed sample of solid sodium carbonate is dissolved in water and titrated using approximately 0.1 M HCl. Phenolphthalein and then bromocresol green indicators will be added to verify that the endpoints located visually, using indicators, are close to the equivalence points.

      In this investigation, gravimetric analysis will be used to precipi- tate and isolate solid CaCO3 from water samples and determine water hardness. Many municipal water treatment plants use soda ash (sodium carbonate, Na2CO3) and lime (calcium hydroxide, Ca(OH)2) to chemically remove calcium and magnesium ions, respectively, from hard water.
