Potassium Oxalate Solubility

Potassium oxalate, represented by the chemical formula K2C2O4, is a salt that is slightly soluble in water. Its solubility at room temperature (25°C) is approximately 1.8 grams per 100 milliliters of water. The solubility of potassium oxalate increases with increasing temperature, with a solubility of about 7.3 grams per 100 milliliters of water at 100°C.

The solubility of potassium oxalate can also be affected by the pH of the solution. At low pH values, the solubility of potassium oxalate decreases due to the formation of insoluble oxalic acid. At high pH values, the solubility of potassium oxalate may increase due to the formation of more soluble complex ions.

It is important to note that the solubility of potassium oxalate may also vary depending on the solvent used. For example, potassium oxalate is more soluble in methanol than it is in water.

Overall, the solubility of potassium oxalate is relatively low and therefore it may be considered as a sparingly soluble salt.
