Abstract Water “hardness” was analyzed in this experiment‚ through the determination of CaCO3 concentration. This was achieved by the titration of an unknown solution using a standardized 0.1M EDTA‚ and addition of Eriochrome Black T to the unknown‚ to indicate the endpoint of the titration. The average concentration of CaCO3 obtained was 1034 ppm‚ with a standard deviation of 2.4495. The results indicate that the unknown solution can be considered as hard water. Introduction The
