if the water is moving, the spreading of the molecules has the aid of the moving water and the experiment will become meaningless

Why did the potassium permanganate crystals start to dissolve in water without being stirred?
because the substance in the potassium permanganate crystals are permeable to water, so that means it will dissolve instantly while poured into water Save
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.
How do you prepare chlorine gas in lab?
Add conncentrated hydrochloric acid dropwise to a beaker containing pottasium permanganate crystals
Is heating potassium chloride crystals a physical or chemical change?
it is as i think a physical change
How would you test for potassium and sulfate ions in the alum?
by adding acids in alum crystals
Can you make fire with potassium permanganate?
You can start a fire by putting a few drops of glycerine onto potassium permanganate crystals.

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
Can you grow crystals with potassium permanganate?
Yes you can it forms purple and black crystals that form acrossed the lens like an army marching.
How does pulverizing speed up the rate of diffusion of potassium permanganate crystals?
By exposing more surface area to the solvent.
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.
Diffusion of potassium permanganate and water?
Potassium permanganate particles diffuse into water molecules and the particles of potassium permanganate mix into water even without stirring. From the higher concentration to lower concentration.
Is potassium permanganate an element?
No, it is a compound. Its chemical formula is KMnO4, and from this we can see that it contains the elements potassium, manganese and oxygen. Potassium permangante is a strong oxidising agent and dissolves in water to give deep purple solutions which may stain hands and clothing. Its crystals are purplish black.
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!
Is KMnO4 soluble or not soluble is cyclohexane?
No the purple solid KMnO4 is only very slightly soluble in the organic liquid cyclohexane.
