4. A 100-ml sample of water is titrated with 0.02 N H2SO4. The initial pH is 9.5 and 6.2 ml of acid is required to reach the pH 8.3 endpoint. An additional 9.8 ml of the acid is required to bring the sample to the pH 4.5 endpoint. Identify the species of alkalinity present and determine the concentration (mg/l) of each expressed as mg/L as CaCO3.
