Sodium Dihydrogen Orthophosphate is a clear, colourless, slightly acid liquid which is soluble in water at all concentrations.

Product Information

The main use of Sodium Dihydrogen Orthophosphate is in water treatment, where it is used for prevention of plumbosolvency. The addition of phosphate at the water treatment works creates a lead-phosphate coating on the inside of lead pipes – this acts as a protective coating and prevents lead from leaching into the water supply.
