Synthesis method
Dissolve 12.6g oxalic acid dihydrate (0.1mol) in 300mL water. Dissolve 18.4g potassium oxalate monohydrate (0.1mol) in 100mL water. Then add the potassium oxalate aqueous solution to the oxalic acid aqueous solution at 3°C and leave it at 0°C for 24 hours. The precipitated crystals are potassium hydrogen oxalate monohydrate.
Purpose
