TITRIMETRIC ANALYSIS
used for standardization after finding out its exact concentration by titration against a standard solution of primary standard. A secondary standard cannot be used for preparing standard solution by direct weighing. Sodium hydroxide and potassium permanganate are examples of secondary standards.

HYDROGEN PEROXIDE ANALYSIS INTRODUCTION
terrificscience.orgPotassium permanganate solution can not be prepared accurately to a fixed concentration. Thus, you must first titrate the solution with a known mass of pure, solid sodium oxalate (for which the number of moles can be calculated to four significant figures). This process is called standardization. The reaction equation is given below. 2MnO 4 ...

29 PRIMARY AND SECONDARY STANDARDS
www.nios.ac.inzAnother example is potassium permanganate (KMnO 4) very often as secondary standard. It is a good oxidizing agent or in other words it is reactive so less stable. More often due to its reactivity, its own oxidized product manganese oxide (MnO 2) contaminates the content. That’s why it is unsuitable for being a primary standard.
