Potassium formate, HCO₂K, HCOOK, or CHKO₂, is the potassium salt of formic acid. This strongly hygroscopic white solid is an intermediate in the formate potash process for the production of potassium. Potassium formate has also been studied as a potential environmentally friendly deicing salt for use on roads
Potassium formate acts as an intermediate in the formate potash process for the production of potassium. It is a deicing salt for used on roads. It serves as a corrosion inhibitor, an anti-scaling agent, a functional fluid, a processing aid and used in petroleum production.
