What is potassium permanganate?
Potassium permanganate is a chemical compound used for a variety of purposes, such as water treatment, medicinal applications, and as a disinfectant. It appears as dark purple crystals or powder and is known for its strong oxidizing properties.
Why did the potassium permanganate crystals start to dissolve in water without being stirred?
Potassium permanganate is highly soluble in water, so it will dissolve without needing to be stirred. The dissolution process occurs due to the attraction between the ions in the crystal and water molecules, causing the crystal to break down and disperse evenly throughout the water.
Why does potassium permanganate dissolve quicker in hot water?
Potassium permanganate dissolves quicker in hot water because the increased temperature of the water speeds up the motion of the water molecules, allowing them to interact more effectively with the permanganate crystals. This increased kinetic energy helps break down the crystal lattice structure of the potassium permanganate, leading to faster dissolution.
How do you prepare chlorine gas in lab?
Chlorine gas can be prepared in the lab by reacting hydrochloric acid (HCl) with manganese dioxide (MnO2) or potassium permanganate (KMnO4). The reaction yields Cl2 gas, which can be collected by downward displacement of air due to its higher density. Caution must be taken when handling chlorine gas due to its toxicity and corrosive nature.
Does potassium iodide conduct electricity?
yes, salt is a very good conductor. The more salt the better. This is true^ But potassium iodide is not salt. Sodium chloride is table salt. Potassium iodide is only electrically conductive in certain forms, aqueous for example. ^ you obviously do not know what a salt is. a salt is an ionic compound that results from the neutralization reaction of an acid and a base. Potassium iodide is a prime example of a salt.
Can you make fire with potassium permanganate?
You can start a fire by putting a few drops of glycerine onto potassium permanganate crystals.
Why does water become coloured when crystals of potassium permanganate are added to it?
Water turns colored when potassium permanganate is added because the potassium permanganate crystals dissolve, releasing the purple permanganate ion (MnO4-) into the water. The permanganate ion absorbs light in the visible spectrum, giving the water a pink or purple color.
Can you grow crystals with potassium permanganate?
Yes, potassium permanganate can be used to grow crystals through a process called recrystallization. By dissolving potassium permanganate in hot water and allowing it to cool slowly, crystals can form. However, the crystals may be small and not as visually appealing compared to other compounds commonly used for crystal growing.
What is the popular term for potassium permanganate?
The popular term for potassium permanganate, an intensely purple glistening crystal, inorganic chemical compound, oxidizing agent, is also known as Condy's Crystals
What is the common name for potassium permanganate?
Yes. Sodium permanganate is an ionic compound comprising mono-atomic sodium cations and polyatomic permanganate anions.
What is the chemical formula for Condys Crystals?
The chemical formula for Condys Crystals is KMnO4, which stands for potassium permanganate.
What would happen to large potassium magnate crystals in water after several hours?
If you think to potassium "permanganate" this compound can be decomposed under the influence of UV radiations.

How a crystal potassium permanganate in a beaker change colour in water within minutes?
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.
What are all the reactions that take place in a potassium permanganate and glycerin reaction?
Reaction of Potassium Permanganate and Glycerine Addition of glycerin to a pile of potassium permanganate produces white smoke and a purple flame. The reaction is not instantaneous, but depends on the fineness of the solid crystals. Equation: 14 KMnO4 + 4 C3H5(OH)3 --> 7 K2CO3 + 7 Mn2O3 + 5 CO2 + 16 H2O Reference B. Z. Shakhashiri, "Chemical Demonstrations", Vol. 1, The University of Wisconsin Press, Madison ,Wisconsin, (1983) p. 83. See the Web Links page for a cool video of the reaction!
