According to http://www.americanelements.com/caoxl.html , calcium oxalate, "CaC"_2"O"_4" is "highly insoluble in water."

No, calcium oxalate, CaC_2O_4, is not soluble in aqueous solution.

The solubility of calcium oxalate is listed at 6.7 mg/L, or 6.7 * 10^(-3)"g/L", far less than the "1 g/L" threshold used to distinguish between soluble and insoluble compounds.

In fact, calcium oxalate is one of the major components of kidney stones.
