Versuchsvorschrift

Solid Potassium Molybdate (K2MoO4) may be prepared by dissolving MoO3 in a basic aqueous solution of potassium hydroxide (KOH) and crystallizing the filtered product to yield potassium molybdate pentahydrate (K2MoO4.5H2O). The anhydrous salt may be prepared by heating to a sufficient temperature to liberate the water.
