When potassium permanganate is dropped into water, it dissociates into potassium ions (K+) and permanganate ions (MnO4-). The permanganate ions further react with water molecules to form manganese dioxide (MnO2), releasing oxygen gas in the process.
HCl is not used as a catalyst in the standardization of potassium permanganate because it can react with permanganate ions, affecting the accuracy of the titration. The standardization process requires a neutral or slightly basic medium to ensure the permanganate titration proceeds correctly.
When potassium permanganate is mixed with hydrochloric acid, the potassium permanganate will react with the hydrogen ions in the hydrochloric acid to form chlorine gas, manganese dioxide, and water. This reaction is exothermic, meaning it releases heat energy. It is important to handle this reaction with caution due to the potential production of chlorine gas, which is harmful if inhaled.
When potassium permanganate crystals are placed in water, they dissolve and release potassium and permanganate ions. These ions react with water molecules to form manganese dioxide, which gives the solution a pink or purple color. The rapid color change is due to the quick reaction of the ions with the water, causing the solution to turn vividly colored within minutes.
Potassium permanganate and bisulfite in stronger acid environment:2MnO4-(aq) + 5HSO3-(aq) + H+(aq) --> 5SO42- + 2Mn2+(aq) + 3H2O(l)Note:Potassium and sodium ions do NOT react, they are tribune-ions.

Benzene decolorizes potassium permanganate because it is a reducing agent. Benzene can donate electrons to the permanganate ions, which causes the purple color of the permanganate solution to fade as it is reduced to colorless manganese ions.
When acidified potassium permanganate is added to a solution containing sodium sulfite, the purple color of the permanganate solution will fade as the permanganate is reduced to colorless manganese(IV) oxide. This reaction occurs because the sulfite ion acts as a reducing agent, converting the permanganate ion to manganese(IV) oxide.
When zinc is added to acidified potassium permanganate solution, zinc displaces manganese from permanganate ions. This reduction reaction causes the purple color of the potassium permanganate solution to fade as the manganese ions are formed. The resulting solution may turn colorless or pink, depending on the concentration of the reactants.
Potassium permanganate is an ionic compound. It consists of potassium ions (K+) and permanganate ions (MnO4-), which are held together by ionic bonds formed through the transfer of electrons from potassium to permanganate ions.
When a small piece of potassium permanganate crystal is dropped into water and heated, it will dissolve and release potassium ions and permanganate ions into the solution. As the temperature increases, the rate of dissolution will also increase, leading to a faster dispersal of the ions. The purple color associated with potassium permanganate will be more pronounced as more of it dissolves.
When potassium and iodine react, they form potassium iodide. The ions involved are K+ (potassium ion) and I- (iodide ion).
Potassium permanganate is acidic in nature. When dissolved in water, it releases hydrogen ions which lower the pH of the solution, making it acidic.
