Description
Sodium hydroxide solution is a volumetric standard at 0,02 mol/l (0,02 N), prepared for titrimetric and analytical work. The solute corresponds to NaOH with CAS number 1310-73-2, molar mass 40,01 g/mol and EG number 215-185-5. Solution density is approximately 1 g/cm³ and the boiling point is about 100 °C, consistent with dilute aqueous alkali. Supplied in a 1 l plastic pack from manufacturer Carl ROTH, this ready volumetric solution supports routine acid–base titrations, standardisation steps and analytical protocols that specify a low-normality sodium hydroxide titrant. Using a defined volumetric concentration reduces preparation variability and helps laboratories maintain traceable working standards. Suitable for teaching, quality control and general analytical chemistry where a 0,02 mol/l NaOH solution is required. Handle caustic solutions with appropriate personal protective equipment and consult the safety data sheet before use.
