## Question:

Titration of {eq}\rm 0.1756\ g {/eq} of primary standard {eq}\rm Na_2C_2O_4 {/eq} required 32.04 mL of a {eq}\rm KMnO_4 {/eq} solution. Calculate the concentration of {eq}\rm KMnO_4 {/eq}.

## Primary Standards:

The primary standards illustrate the class of substances which are "pure and stable." They played a vital role in preparing "secondary standard solutions." They have stable concentration so can be used to determine "concentration in titration."
