Potassium acetate
Potassium acetate (CH3COOK) is deliquescent white crystalline powder which is soluble in water (and many other solvents). Aqueous solutions of potassium formate have pH between 7.5-9.0 which makes slightly alkaline to a near neutral pH which is not caustic or corrosive unlike bromide, fluoride, chloride, nitrate, hydroxide, sulfate, thiosulfate or carbonate salts, which are either strongly acidic or basic.
