Strontium oxalate can exist either in a hydrated form (SrC 2 O 4 ·nH 2 O) or as the acidic salt of strontium oxalate (SrC 2 O 4 ·mH 2 C 2 O 4 ·nH 2 O). [2] Strontium oxalate is soluble in 20 000 parts of water; in 1 900 parts of 3.5% acetic acid, in 115 parts of the 23% acid, but less soluble in the 35% acid; readily soluble in diluted HCl ...
