Potassium lactate is a salt formed from potassium and lactic acid. It is commonly used as a food additive, particularly

Sodium thiosulfate (Na2S2O3) is an inorganic compound that is commonly used as a photographic fixer, as well as in medical and industrial applications. It is a white crystalline powder that is soluble in water and has a mild odor. In photography, sodium thiosulfate is used to remove unexposed silver halide from photographic prints and negatives, making the image permanent. In medicine, it is used as an antidote for cyanide poisoning, and in industrial applications, it is used as a reducing agent, a dechlorinating agent, and in water treatment processes.
