explain why it is important to rinse the buret with KMnO4 solution twice before titration? And why you should rinse buret with water thoroughly before you leave?
Homework Answers
Before the titration we have to rinse the buret with KMnO4 because the rinsed buret is with some water and we filled with KMnO4 the water in the buret will dilute to some extent to our KMnO4 solution.
So the original KMnO4 is rinsed for the first time,the same water may interfere in the next solution also so it is filled for the second time also.
After completion of the titration the buret is rinsed with water because some of the KMnO4 is along the walls of the the buret so it may interfere in the next experiment

Titration and standardization 50mL buret is filled with 50mL of 1M NaOH solution (6.02g of NaOH in 150mL water). 1.55g of KHP is completely dissolved in water. Then titration of NaOH solution is done into KHP solution. 1) How do you standardize NaOH with KHP data? 2) How do you determine the volume of NaOH required to neutralize the KHP solution? 3) How do you determine the molarity of the sodium hydroxide solution?
