## Abstract The determination of phosphate in the presence of hydrochloric acid with Cavell's ammonium vanadateβammonium molybdate reagent^2^ has been studied and made quantitative.

The most widely used method for the determination of silicon and phosphorus is the spectrophotometric method. This involves the formation of the yellow silicomolybdate and phosphomolybdate, followed by reduction of these complexes to molybdenum blue. During the investigation leading to the colorime
