Question

Determination of molarity of potassium permanganate solution using mohr's salt by volumetric analysis

Answer 1

Explanation:

Scale about 0.2g solid KMnO4 on balance, put it in a 500mL of beaker, add 250mL of distilled water into it, heat and stir it until the solid is dissolved completely. After the solution turn co1d, pour it into a brown reagent bottle, shake it even and block it up tightly with the cork.

Answer 2

Answer:

KMnO4 acts as a good oxidising agent in acidic medium. If acid is not used KMnO4 may be oxidised to MnO2 giving a brown precipitate.
