Sodium hydroxide solution, 25 %, p.a., 1 l, plastic

Sodium hydroxide solution 25 %, p.a. is an analytical-grade aqueous base corresponding to CAS number 1310-73-2 and empirical formula NaOH. The preparation shows a molar mass of 40,01 g/mol for NaOH, a density of 1,27 g/cm³, and a boiling point of 100 °C, giving clear physical reference data for laboratory use. a. solution supports titrations, pH adjustment, saponification, cleaning protocols, and general inorganic and analytical chemistry workflows. The defined 25 % concentration simplifies dosing and standardisation steps where a reliable sodium hydroxide reagent is required. Suitable for research, teaching, and quality-control laboratories that specify p.a.-grade NaOH solution in plastic packaging for everyday wet-chemistry applications.
