Sodium hydroxide is a compound which comes in form of a white solid (usually in form of granules) at standard conditions. Sodium hydroxide has many applications. Due to its alkalinity, it is used as a pH regulator. It is also important in the production of paper, soap and detergents. In the chemical industry it is used in the production of many other compounds. It is also used as a household cleaning agent. Sodium hydroxide also has various applications in the food industry as well.

Sodium hydroxide can be found in form of a solution in most grocery stores. Such solutions are used for cleaning and for drain opening. It can also be found in stores which sell paint, varnishes and similar products, since it is also used as a paint stripper. Sodium hydroxide of higher purity could eventually be ordered from drugstores/pharmacies or from chemical selling companies.
