Description
Sodium hydroxide solution, 2 mol/l – 2 N, volumetric standard solution
Volumetric Standard Solutions
A volumetric standard solution is a solution containing a precisely known concentration of a substance. The concentration of a volumetric standard solution is determined using a primary standard, which is accurately weighed and dissolved to make a specific volume. Volumetric standard solutions are made using reagent-grade (p.a.) substances as source materials.
Volumetric Standard Solutions, ready-to-use
The advantages of this over making them yourself are:
- Manufactured and tested using modern manufacturing and analytical methods
- Ready-to-use solutions
- High accuracy for precise analyses
- Application of NIST-certified reference substances for checking
- Connection to standard titrators is possible
