What is Sodium Hydroxide?
Sodium Hydroxide is a solid ionic compound. It is also known as caustic soda, Iye, sodium hydrate or soda lye. It is a co product of chlorine production. In its pure form it is crystalline solid, colorless in nature. This compound is highly water soluble and consists of sodium cations and hydroxide anions. NaOH absorbs moisture from the air. It is highly corrosive and can cause severe skin burn and irritation to eyes and other body parts. It generates high level of heat and so is always created by mixing the compound into water not not the vice versa. In cosmetics, this inorganic compound is used as a buffering agent. It can also control the PH levels. The PH of sodium chloride is 13.
