4 Ιουν 2018 · Learn the guidelines to prepare and standardize the volumetric solutions for chemical analysis in Pharmaceuticals. It is not always possible nor is it essential, to prepare volumetric solutions of a desired theoretical molarity.
Volumetric solutions are standardised by the methods described below. When a volumetric solution is to be used in an assay in which the end-point is determined by an electrochemical process (for example, amperometry or potentiometry) the solution is standardised by the same method. The composition of the medium in which a
Use commercially available volumetric standard solution. Standardize the solution as follows. Accurately weigh about 0.2 g of sodium oxalate, primary standard, previously dried for 2 hours at 105, and dissolve in 75 mL of water.
