Potassium Phosphate Mono

Sodium Phosphate Tribasic Dodecahydrate ACS

Note: This reagent, when stored under ordinary conditions, may lose some water of crystallization. Any loss in water will result in an assay of more than 100% Na3PO4.12H2O but does not affect the determination of the relative amount of free alkali present.

GENERAL DESCRIPTION

Typical appearance: colorless or white solid

Analytical use: buffer; sequestering agent

Change in state (approximate): melting point, 75 °C
