Sodium hydroxide (NaOH) is a common inorganic compound with a molecular weight of 39.997 g/mol, formed from Na+ and OH- ions. It has a melting point of 318oC, a boiling point of 1390oC and a density of 2.13 g/mL[1]. Typically a white crystalline odorless solid at room temperature, it forms sodium hydroxide solution in water. Highly corrossive, NaOH can induce severe burns on differents parts of the body such as the skin. Some applications include electroplating and oxide coating[2].
