Phosphate with AgNO3

Transmitted Near Crossed Circular Polarized Light Illumination

The presence of phosphate ions in solution can be determined by the addition of a small droplett of 10% silver nitrate solution at the edge of the test solution.

Significance in the Environment:
This example was created by adding the silver nitrate test solution to a dilute solution of an unknown precipitate removed from a concentated sodium hypochlorite solution and dissolved in dilute nitric acid.
