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 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
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 happen when potassium permanganate is added to butter?
it will get fire slowly
Why does acidified potassium permanganate turn from purple to colorless when added to an alkene?
The purple colour is the Manganese in oxidation state '+7'. This oxidation state is reduced to '+2' ,which is pale green/colourless, when reacted with the alkene. Hence the change of colour.

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

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 is the equation when a saliva is acidified with HCl and BACl. acidified with HNO3 and added with NH4MoO4. acidified with HCl and added with NH4C2O4?
saliva acidified with HCl and BaCl: Ba++ + SO42- ---> BaSO4 saliva acidified with HNO3 and added with NH4MoO4: H2PO4- + 12MoO42- +3NH4 +22 H3O+ ---> (NH4)3 + 12MoO3 + 34H2O saliva acidified with HCl and added with NH4C2O4: Ca++ + C2O4 ---> CaC2O4
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.
Which acid must be added to potassium dichromate to acidify it?
Potassium Dichromate (VI) can be acidified with sulphuric acid AND hydrochloric acid! Note that another common oxidising agent ' Acidified Potassium Manganate (VII)' is sometimes used although this one can only be acidified with sulphuric acid not hydrochloric as the Manganate (VII) oxodises the Cl- ion instead!
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.
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.
What happens when chlorine is added to silver nitrate and potassium chloride?
When clhlorine is added to silver nitrate a milky white precipitate of Silver Chloride is formed. Potassium nitrate is also formed. When chlorine is added to potassium chloride nothing visible happens but the solutiuon become more acidic.
