Potassium formate is colorless transparent liquid or white solid, very easy to absorb moisture, with reducing properties, can react with strong oxidizing agents, density 1.9100g/cm3, soluble in water, saturated and the specific gravity of the solution is 1.58g/cm3, non-toxic and non-corrosive. Carbon monoxide and potassium hydroxide can be synthesized by heating together with potassium formate, further acidification and distillation obtained formic acid.
Potassium formate plays an important role in plant growth by promoting nutrient uptake and increasing the rate and quality of plant growth. At the same time, potassium formate can also increase the resistance of plants, which plays a positive role in plants suffering from environmental stresses such as drought and high temperatures.
