WebA simple standard is obtained by the dilution of a single element or a substance in a soluble solvent with which it reacts. A primary standard is a reagent that is extremely pure, stable, has no waters of hydration, and has high molecular weight. Some primary standards of titration of acids include sodium carbonate. Uses WebBecause the grignard reagent acts as a carbanion (have two lone pair of electrons on a carbon), it is highly reactive and a strong nucleophile. Because of this, if we were to use water as our solvent, which contain hydrogens that are easy to steal by the carbanion, we would lose our grignard reagent and can no longer complete the reaction.
