Potassium formate, HCO₂K, HCOOK, or CHKO₂, is the potassium salt of formic acid. This white solid is an intermediate in the formate potash process for the production of potassium.^[2] Potassium formate has also been studied as a potential environmentally friendly deicing salt for use on roads.^[3]^[4]
