measuring the amount of metal carbonate in an ore

Water Hardness S'05 chemistry.bd.psu.edu

The purpose of this experiment is to determine the hardness of a water sample by measuring the amount of calcium present. This analysis will utilize the method of titration. i.e. not bound to any metal, is blue. A small amount of indicator is added to the solution containing the Ca2 this experiment you will measure calcium carbonate
