Commonly often, Caustic soda identified as sodium hydroxide, Is a non-organic substance that contains the formula naoh. Often identified, Sodium hydroxide as lye and caustic soda, Is an inNaturally occurring substance represented by the formula naoh. It manifests itself as a solid white substance ionic compound consisting of sodium and hydroxide, Cations na anions oh . Sodium hydroxide functions as a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burnsIt serves as highly dissolves easily in water and easily takes in moisture and carbon dioxide from the air. It creates a set of hydrates naoh nh2o. 11 the monohydrate naoh h2o crystallizes from water solutions between 12. 3 and 61. 8 c. The commercially available sodium hydroxide is often this monohydrate, And published data may refer to it in place of the anhydrous compound
