Caustic soda lye, also known as sodium hydroxide solution or caustic soda solution, is a liquid form of sodium hydroxide (NaOH) that is dissolved in water. It is usually a clear, colorless liquid with a slippery feel and high viscosity. The solution is highly hygroscopic, which means it can absorb moisture from the air. The concentration of sodium hydroxide can vary and is often expressed as a percentage by weight or molarity. This solution is highly alkaline and finds wide applications across different industries.
