Phosphate dissolves all the suspended solids by making soluble complex compounds which may precipitate at pH higher than 11. Phosphate: 6-8 ppm. Conductivity: < 50 micro-siemens/cm. CC. Run SPC for all water parameters and monitor all the parameters within a defined span. WebAs the pH of a phosphate solution becomes more acidic than pH 7 or more basic than pH 11, the hydrolysis rate increases dramatically. Metal ions: The presence of multivalent metal ions has been reported to catalyze reversion rates. As the concentration of Ca++ or Al++ or Fe++ increases, reversion rates increase.
