Why is the rate of diffusion not identical when potassium permanganate is added to warm and cold water?

The heat allows the particles to move more freely in the water and therefore diffuse faster. When the water is colder the particles move more slowly and therefore the rate is slower. I hope this helps, I'm practicing this concept as well.

What happen when potassium permanganate is added to butter?
it will get fire slowly
Does the colour of potassium permanganate persist when it is added initialy to heated 3ml of ethanol?
When potassium permagnate is added initially to ethanol, ethanol gets oxidised into ethanoic acid using potassium permagnate. Thus, decolorizing potassium permagnate. When excess is added , the color of potassium permagnate persists.
What happens to the colour of water when potassium permanganate is added?
according to the amount we put the change from dark purple to pink color
What is the balanced eq when potassium permanganate is added to sodium bisulfite?
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.
Why the color of potassium perpanganate disappears if it is added to warm solution of ethanol?
When potassium permanganate reacts with ethanol, it releases oxygen. ie, an atom of oxygen thus converting the ethanol to acetic acid. Initially colour disappears because coloured permanganate ions of potassium permanganate are consumed to oxidise ethanol. C 2 H 5 OH (WITH ALKALINE KMnO 4) CH 3 COOH+H 2 O Remember :When excess is added colour does not change because there is no more alcohol left and hence there is no reaction.

Acidified solution potassium permanganate added solution sodium sulfite?
Potassium permanganate and sulfite:2MnO4-(aq) + 5SO32-(aq) + 6H+(aq) --> 5SO42- + 2Mn2+(aq) + 3H2O(l)Note:Potassium and sodium ions do NOT react, they are tribune-ions

What is the test for unsaturation?
Add KMnO4 (Potassium Permanganate) which is a purple solution. If it is added to an alkene or alkyne it will turn colourless and produces a brown precipitate.

What happens when zinc is added to the acidified potassium permanganate?
3 Zn + Cr2O72- + 14 H+ → 3 Zn2+ + 2 Cr3+ + 7 H2O
What is a chemical equation when potassium permanganate gets decolourized when added to an acidified solution of ferrous sulphate?
2KMnO4 + 8H2SO4 + 10FeSO4 -----> 5Fe2(SO4)3 = 2MnSO4 = K2SO4=H2O
Why is it important to leave the water to become completely still before potassium permanganate crystals can be added?
if the water is moving, the spreading of the molecules has the aid of the moving water and the experiment will become meaningless
What happens when zinc dust is added to an acidified solution of potassium permanganate?
KMno4 is reduced to Mn^2+ Salt and the pink colour is discharged by the nascent hydrogen produced when zinc reacts with h2so4
What are the uses of potassium permanganate?
Potassium permanganate may be added with water and used as a disinfectant in the treatment of skin disorders. It can be used to remover sulphides and iron form well and waste water. It is used in the synthesis of ascorbic acid, saccerine and others. If mixed with concentrated hydrochloric acid it will produce chlorine gas. Mixed with concentrated sulphuric acid it becomes explosive.
