From the presence of sulfuric acid, silver sulphate, and mercury sulphate, potassium dichromate oxidises the natural and organic matter contained within the water sample to produce carbon dioxide (CO2) and water (H2O). The amount of potassium dichromate utilised is decided by evaluating the volumes of ferrous ammonium sulphate consumed during blank
