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.

Why did the potassium permanganate start to dissolve without being stirred?
Potassium permanganate is water-soluble and therefore will dissolve in water without stirring due to its high solubility, even without additional agitation. The dissolution process is driven by the interaction between the water molecules and the potassium permanganate particles without the need for external stirring.
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.
Is potassium permanganate ionic or covalent?
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.
Is potassium permanganate and water solution or suspensions?
Potassium permanganate and water form a solution, unless here is so much potassium permanganate present compared to the amount of water that the solubility limit is exceeded. In the latter instance, there might be both solution and suspension.
Why does the purple colour spread when a crystal of potassium permanganate is placed in water?
The purple color spreads when a crystal of potassium permanganate is placed in water due to the dissolution of potassium permanganate molecules in water. Potassium permanganate is a highly soluble compound, and its purple color comes from the permanganate ions in the crystal dispersing in the water. This dispersion allows the purple color to be visible throughout the water.
How do you prepare 0.1N potassium permanganate?
To prepare 0.1N potassium permanganate solution, dissolve 3.16 grams of potassium permanganate in 1 liter of water. This will give you a solution with a normality of 0.1N.
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.
What happen if the potassium permanganate solution drop to the water?
If potassium permanganate solution is dropped into water, it will dissolve and create a purple or pink solution. Potassium permanganate is a strong oxidizing agent and can be used for various applications such as disinfection and water treatment.
Can potassium permanganate dissolve in water?
Yes, potassium permanganate is highly soluble in water. It dissolves readily to form a purple solution.

How do you Prepare 0.02 N potassium permanganate solution?
To prepare a 0.02 N potassium permanganate solution, you would need to dissolve 1.58 grams of potassium permanganate (KMnO4) in 1 liter of distilled water. This will give you a solution with a molarity of 0.02 N. Remember to wear appropriate personal protective equipment when handling potassium permanganate, as it can be harmful.
How long does potassium permanganate take to dissolve in water?
Potassium permanganate typically dissolves in water within a few minutes, as it is a highly water-soluble compound. Agitating the solution or using warm water can help speed up the dissolution process.
What happens to the ions when potassium permanganate are dropped into water?
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.
Is potassium permanganate ionic or covalent?
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.
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.
Is potassium permanganate and water solution or suspensions?
Potassium permanganate and water form a solution, unless here is so much potassium permanganate present compared to the amount of water that the solubility limit is exceeded. In the latter instance, there might be both solution and suspension.
