Sodium Hydroxide (NAOH) has molecular mass of 39.997 g/mol

Sodium Hydroxide (NaOH) is a chemical compound which is stongly alkali and can be dissolved in water meaning that it is aqueous. Because of this, and its ability to penetrate deep into the skin, NaOH can be known as a caustic. This means the substance can penetrate the skin slowly creating deep chemical burns causing inflammation. There are also medical uses for this substance, such as removing dead tissues and growths such as warts [1].

Chemical Properties

Due to NaOH's alkali properties, it can react with acids to creat salts.

NaOH + HCl ---> NaCl + H2O

These are neutralisation reactions as the acidic OH group reacts with the acidic H group to create water. This then leaves oppositely charged ions which through ionic bonding and electrostatic forces of attraction create a salt [2].

The name of the compound NaOH is sodium hydroxide.
