Phosphate as PO4 Test Kit

Procedure: Small amount of sample is collected in a test tube and the corresponding reagent is added to the sample. Color of the sample changes and the same is compared with the respective color chart. The reading of the matched color on the color chart is the concentration of the respective parameter in the water.

Under acid conditions soluble phosphate react with ammonium molybdate and produce molybdophosphate acid, which in turn gets reduce to molybdenum blue after addition of reducing agent such as stannous chloride, which is directly proportional to phosphate concentration.
