Dear ResearchGate Team
We are working on the synthesis of the compound Li6[α-P2W18O62]·28H2O. First step is the dissolution of lithium tungstate Li2WO4 in boiling water. However, our >99% pure compound does not tend to dissolve, it creates a white-milky suspension when stirred. We heated it at 100 C for almost 12 hours, with and without ultrasound bath. Can anyone help with dissolving this compound? We took 51g of LiWo4 and 80 mL DI.
Thanks and Best regards

Tungstic acid (H2WO4) is rather insoluble in water, and a weak acid. Li2WO4, as the salt of a strong base and a weak acid, is probably hydrolyzed, especially in boiling water.
Try to add an excess of LiOH to the milky suspension, just enough to clarify it.
