Description
colourless crystals Calcium oxalate is white precipitate, insoluble in weak acids, but soluble in strong acids, formed by reaction of soluble calcium salt solution and ammonium oxalate solution. Solubility at 18 °C 0.0056 g anhydrous salt per liter of saturated solution.
Calcium oxalate is the calcium salt of oxalic acid, which in excess in the urine may lead to formation of oxalate calculi (kidney stones). It contains an oxalate(2-).|The calcium salt of oxalic acid, occurring in the urine as crystals and in certain calculi.
