What is sodium molybdate? I just know about them in these days. I gert new things from it, that is a great thing and I like it. Sodium molybdate is always used as What is it ? Sodium molybdate, Na2MoO4, is useful as a source of molybdenum. It is often found as the dihydrate, Na2MoO4·2H2O. The molybdate anion is tetrahedral. Two sodium cations coordinate with every one anion. History: Sodium molybdate was first synthesized by the method of hydration.  A more convenient synthesis is done by dissolving MoO3 in sodium hydroxide at 50–70 °C and crystallizing the filtered product. The anhydrous... ...Read More>>
