Aluminum carbonate is a chemical compound with the formula Al2(CO3)3. It is a white, crystalline solid that is insoluble in water. Aluminum carbonate is not commonly encountered in pure form due to its high instability, especially in the presence of water and carbon dioxide. Instead, it tends to decompose into aluminum hydroxide and carbon dioxide when exposed to moisture or acidic conditions.

Ammonium chloride is an inorganic compound with the chemical formula NH4Cl. It is a white crystalline salt that is highly soluble in water and has a salty taste. Ammonium chloride is often used in various industrial and laboratory applications, including as a flux in soldering, as a nitrogen source in fertilizers, and as a component in dry cell batteries. It can also be used in medicine as an expectorant to help thin and loosen mucus in the respiratory system

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.
