Potassium formate (HCOOK) is a white, hygroscopic, readily biodegradable, and environmentally safe salt. When compared with traditional fluoride, chloride, bromide, sulfate and nitrate salts, HCOOK offers high solubility (3.3g/mL water), high density, alkaline pH (7.0-8.5 @ 25°C, 1 M in H2O), lower crystallization temperature,viscosity lower than LiBr, low latent heat of absorption, less corrosive than chloride-based salts, and negligible vapor pressure. Because of such versatile properties.
