Physical properties: It is an odorless, white crystalline solid with a density of 2.13 g/mL, and melting point of 318 °C. It is widely available as pellets, flakes, granules, and also as aqueous solutions of different concentrations.
Chemical properties: Sodium hydroxide is soluble in polar solvents such as water, ethanol, and methanol, and insoluble in organic solvents. Dissolving solid NaOH in water is a highly exothermic reaction and the resulting aq. NaOH solution is a colorless, odorless and important base used in the laboratory. As a strong base, sodium hydroxide readily reacts with acids such as HCl, to form the corresponding salts, as shown below:
NaOH + HCl → NaCl + H2O
Sodium hydroxide is very hygroscopic (absorbs water from air) and also absorbs carbon dioxide from air.
