Lithium chromate, Li₂CrO₄

The dihydrate, Li₂CrO₄,2H₂O, is obtained by dissolving lithium carbonate in chromic acid. It forms rhombic plates, with high polarizing power; and is converted at 150° C. into needles, probably the anhydrous salt and isomorphous with the corresponding sulphate and selenate. It yields a double salt with potassium, LiKCrO₄. At 18° C., 100 grams of water dissolve 110.9 grams of the dihydrate.

A lithium dichromate has also been prepared.
