Sodium Hydroxide Definition
Sodium hydroxide, also known as lye and Caustic Soda is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na+ and hydroxide anions OH−. Sodium hydroxide is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water, and readily absorbs moisture and carbon dioxide from the air. It forms a series of hydrates NaOH·nH2O. 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 instead of the anhydrous compound. As one of the simplest hydroxides, it is frequently utilized alongside neutral water and acidic hydrochloric acid to demonstrate the pH scale to chemistry students.
NaOH or Sodium Hydroxide or lye are thin white sheets that are moisture absorbent and soluble in water. It is derived from the evaporation of liquid Sodium Hydroxide, which is itself produced through membrane technology.
Sodium hydroxide or Lye with NaOH chemical formula, a solid white solid with a melting temperature of 2°C and a density of 0.5 Perk profits can easily absorb moisture from the air and, therefore, have to be protected during transportation.
