Last updated date: 01st Apr 2024 • WebSodium hydroxide is a white hygroscopic solid and is one of the strongest bases. In water it dissolves very well under great heat generation due to the negative enthalpy of solution of -44.4 kJ/mol to the strongly alkaline reacting sodium hydroxide solution (pH 14 at c = 1 mol/L). It is always completely dissociated in aqueous solution.
