KMnO 4 (Potassium Permanganate) - It is prepared from the mineral pyrolusite (MnO 2 ). The preparation involves following ste..

Experiment 2: Place some crystals of potassium permanganate at the bottom of a beaker. Slowly transfer water into the beaker with the help of a pipette. After sometime a dense purple solution is formed at the bottom and you will notice that it gradually spreads with the rest..

1. Iodine is used as antiseptic in the form of an alcoholic solution, which is known as tincture of iodine. 2. It is also used for the preparation of iodoform and potassium iodide. 3. Iodide ion is necessary for the normal functioning of the thyroid gland insufficient..

Chlorine is prepared by the oxidation of concentrated hydrochloric acid using oxidising agents like manganese dioxide, lead dioxide, trilead tetra oxide, potassium permanganate and potassium dichromat..

Rates of chemical reaction depends on the inherent characteristics or nature of the reactants. That is the reason, why some reactions are fast while others are slow. For E.g., oxidation of ferrous ion by KMNO 4 (potassium permanganate) in acidic medium is fast, while the ..

Tests for Chlorine - 1. Chlorine is a greenish yellow gas with a pungent and irritating odor. 2. It turns wet blue litmus paper red and then bleaches it. 3. Colored petals and the leaves of plants can be bleached by it. 4. Chlorine turns wet starch potassium iodide paper blue by..
