Primary standard are the compounds having reagent(analyte)
of high purity and can directly used for perpration of
standard solutions.
Example:- Nacl is primary standard for AgNO3
NaOH is primary standard for HCl
Secondary Standard solutions are analysed against primary
standard solutions. Basically these are perpared in
laboratory for specific analysis.
