chemical oxygen demand test Secrets

From the existence of sulfuric acid, silver sulphate, and mercury sulphate, potassium dichromate oxidises the organic subject contained during the h2o sample to produce carbon dioxide (CO2) and h2o (H2O). The amount of potassium dichromate utilised is decided by evaluating the volumes of ferrous ammonium sulphate eaten throughout blank and sample t
