Why kmno4 must be standardized before use




















Hence, based on the above theory our aim is to prepare and standardize potassium permanganate solution with oxalic acid.

Apparatus: Watch glass,. Beaker — ml. Glass wool. Cleaned and calibrated volumetric flask — ml. Conical flask. Electronic balance. Chemicals: Potassium permanganate AR grade. Oxalic acid AR grade. Preparation of Potassium permanganate solution. Weigh 3. Transfer the contents to a ml beaker containing cold distilled water and stirred thoroughly, breaking up the crystals with a glass rod to effect solution.

Decant the solution through a small plug of glass wool supported in a funnel into a ml volumetric flask. Add more distilled water to the beaker and repeat the above process till all the potassium permanganate gets dissolved.

Make up the volume and shake well so as to affect uniform mixing. Keep the flask with stopper for 24 h and then filter through asbestos. The organic matter present in the distilled water is decomposed by potassium permanganate resulting in the formation of MnO 2 during 24 h. Keep the filtered solution in a dark glass bottle.

Standardize the solution 24 h after its preparation. Standardization of potassium permanganate solution. And the purpose of its standardization and how? This is what we will discuss in this article. Odor No smell but has a sweet taste. Solubility in water 6. Chemical Properties: Potassium permanganate is an inorganic chemical compound.

The equations representing oxidation in these media are as follows:. Concentrated hydrochloric acid makes chlorine. Note: The manganese containing products from redox reactions depend on the PH. MnO 4 2- is reduced. On heating permanganate crystals decompose to release oxygen. Home Philosophy Purpose. Academic anxiety? Get original paper in 3 hours and nail the task.
