1. Description:

Sodium hydroxide (NaOH), also known as lye and caustic soda,[1][2] is an inorganic compound. It is a white solid and highly caustic metallic base and alkali salt which is available in pellets, flakes, granules, and as prepared solutions at a number of different concentrations.[10] Sodium hydroxide forms an approximately 50% (by weight) saturated solution with water.[11]
Sodium hydroxide is soluble in water, ethanol and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air.
Sodium hydroxide is used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents and as a drain cleaner. Worldwide production in 2004 was approximately 60 million tonnes, while demand was 51 million tonnes.[12]

3 . Usage

Sodium Hydroxide is a extremely important compound in our lives because it has so many uses. It is a very common base used in the chemical industry and is used for many things, many of which occur in our daily lives. One of the most well known uses of Sodium Hydroxide is its use in unclogging drains. It comes in many different brands of drain cleaners, but one of the most common is Drano. It also comes in the form of lye soap which can be used to wash practically anything, from the dishes to your face.

Sodium Hydroxide is also used quite a bit in food processing. The compound is often used in steps for peeling fruits and vegetables, processing cocoa and chocolate, thickening of ice cream, poultry scalding and soda processing. Olives are soaked in Sodium Hydroxide along with other substances to make them black, and soft pretzels are also coated with the compound to give them a chewy texture.
