Why is calcium oxalate insoluble? Calcium oxalate is a combination of calcium ions and the conjugate base of oxalic acid, the oxalate anion. Its aqueous solutions are slightly basic because of the basicity of the oxalate ion. The basicity of calcium oxalate is weaker than that of sodium oxalate, due to its lower solubility in water.
Why are oxalates insoluble? Plenty of foods contain oxalates. … The reason why the majority of people have no issue with oxalates is because any free oxalate (in the form of oxalic acid) becomes bound to minerals in the gut, making most of the crystals insoluble.
