what ia difference between primary standard solution and secondary standard solution? (2024)

Be yourself 5th Jan, 2020

Hello

Primary standard solutions are solutions made out of primary standard substances. A primary standard is a substance of known high purity (99.9% pure) which may be dissolved in a known volume of solvent to give a primary standard solution. Primary standards are reagents that can involve in chemical reactions. These compounds are often used to determine the unknown concentration of a solution that can undergo a chemical reaction with the primary standard.

A secondary standard solution is a solution that is made specifically for a certain analysis. A secondary standard is a substance whose active agent contents have been found by comparison against a primary standard. This means it is usually standardized against a primary standard.

Secondary standard solutions are used to calibrate analytical equipment and analytical techniques.
