Titrate it with a primary standard
A solution that has been titrated against a primary standard solution.
Primary standard is a chemical entity available with highest purity and stability with high molecular weight. e.g. KHP, NaCl, Calcium salt used in standardisation of volumetric solution. Secondary standards are compounds used in analysis after evaluation against primary standards. e.g.- NaOH VS, Sodium thiosulphate VS

HCl is not used as a primary standard
It is primary standard is a substance that has a known high digree of purity ,reatively large molar mass ,is nonhygroscopic and reacts in a predic table way.
In order for a substance to be a primary standard it must be able to dissolve in water. Since iodine is unable to do this it cannot be used as a primary standard
HCl is a gas which is dissolved in water to form the solution the concentration expressed is very approximate so its not a primary standard.
A primary standard substance is referred to a reagent which is pure. This is a substance that can be weighed easily due to its purity.
Primary standard can be defined in metrology, as a standard that is accurate enough that it is not calibrated by or subordinate to the other standards. Primary standards are used to calibrate other standards.
Either full synthetic or standard primary oil.
what is the advantage of potassium iodate as aprimary standard
Yes, indeed it does. The primary way to counteract this, though, is to keep well hydrated.
The primary hydrate of copper sulfate is the pentahydrate of copper (II) sulfate, with formula CuSO4.5 H2O.
HCl, hydrochloric acid, is the primary standard used to titrate against potassium hydroxide.
