WebProduct name : Sodium Hydroxide, 50% w/w CAS-No. : 1310-73-2 Product code : LC24150 Formula : NaOH Synonyms : caustic soda 50% W/W / soda lye, 50%, aqueous solution / … 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.
