Titrating the Unknown. Used deionised water to bring to the mark of a 50ml volumetric flask. (Hv0.1)
The average concentration of CaCO3 obtained was 1034 ppm with a standard deviation of 2.4495. Carried out titrations on each prepared river sample. View PDF.

The kinetics of the indicator reaction are slow; heating aids in speeding up the transition from red to blue. Ca +2 + EDTA -4 - -----> CaEDTA -, A molecule of EDTA has 4 carboxyl groups (COOH) attached on its outer part. carbonate is classified as soft= (Hardness of water, n.). Determination of Hardness: Hardness is expressed as mg/L CaCO 3.
