HCl, hydrochloric acid, is the primary standard used to titrate against potassium hydroxide.
what is the advantage of potassium iodate as aprimary standard
Usually sodium hydroxide is used, as it is the cheapest and most commonly available base you will find in chemistry labs.
because it easily ionises itself.
Sodium hydroxide easily absorb water and carbon dioxide.
it is primary standard........ but before making solution dry it at 120. C
sodium hydroxide is a secondary standard because it absorb the moisture from the air and its concentration will change

- dipotassium hydrogen phosphate is used to prepare buffers - for chemical analysis by spectrometry standard solutions of potassium exist

A solution that has been titrated against a primary standard solution.
KHP (potassium hydrogen phthalate) is available extremely pure (which is always good for a primary standard) and gives a very sharp end-point especially with Crystal Violet Indicator
Potassium dichromate is used as the primary standard for UV spectrophotometry because of its properties. It is pure, stable, has no waters of hydration, and has a high molar mass.
we use primary standard apparatus in chemistry lab to find accurate resultthe examples of primary standard apparatus arepippetteburreteVolumetric Flask
