Answer Posted / narasimha murthy
A primary standard is a reagent that is extremely pure,
stable, has no waters of hydration, and has a high
molecular weight
A secondary standard is a standard that is prepared in the
laboratory for a specific analysis. It is usually
standardized against a primary standard.
