A primary standard is a reagent that is extremely pure, stable, has no waters of hydration, and has a high molecular weight.
primary standard solution is prepared by direct measurements of the mass of solute and the volume of solution.whereas, a secondary standard solution is a solution whose concentration can't be determined directly from weight of solute and volume of solution, the concentration must be determined by analysis of the solution itself.
The two main types of standard solutions are primary standard solutions, which are highly pure and stable substances that can be used to make precise titrations, and secondary standard solutions, which are solutions prepared using a primary standard solution as a reference for their concentration.
A standard solution in titration is a solution of known concentration that is used to determine the concentration of another solution. It is typically a primary standard that can be accurately weighed and dissolved to make a solution of precise concentration. Standard solutions are essential in titration to accurately measure the volume of the solution being titrated and calculate its concentration.
It is necessary to standardize a solution of NaOH using a primary standard like KHP because primary standards are highly pure and have a known exact mass. This allows for accurate and precise determination of the concentration of the NaOH solution, ensuring reliable and consistent results in experiments.

A primary standard solution is generally a solution prepared and certified by an authorized and specialized institution (for example: NIST - National Institute for Standards and Technology).

No, sodium thiosulfate solution is not typically considered a primary standard. It is commonly used as a titrant in redox titrations rather than as a primary standard due to its susceptibility to oxidation by air. Primary standards are typically pure, stable compounds that can be used to standardize solutions.

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 typically used as a primary standard because it is difficult to obtain in a pure solid form. Instead, it is usually standardized against a primary standard such as potassium hydrogen phthalate (KHP) or sodium carbonate.
