It behaves like a firework - and reacts very vigorously with the evolution of carbon dioxide and heat. Water is also evolved but because of the heat it comes off as steam. The equation is
3 C3H5(OH)3 + 14 KMnO4 ---à 14 MnO2 + 14 KOH + 9 CO2 + 5 H2O
It DOES NOT need heat to do this. After about 10 seconds this reaction will occur. Heat will accelerate the process and make it much more dangerous.
What else can I help you with?
Which gas is given off when potassium permanganate is broken down?
Oxygen gas is given off when potassium permanganate is broken down. Potassium permanganate decomposes into manganese dioxide, potassium hydroxide, and oxygen gas when heated.
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.
Does potassium permanganate and copper sulphate undergo sublimation?
No, potassium permanganate and copper sulfate do not undergo sublimation. Sublimation is the process in which a substance transitions directly from a solid to a gas without passing through a liquid phase. Potassium permanganate and copper sulfate undergo a different process known as decomposition when heated.
When potassium permanganate is dissovled in water and heated what is the color of the disillate and original solution?
The original solution is an intense violet color because it contains dissolved potassium permanganate. The distillate is clear (colorless) because only the water distills and the potassium permanganate is left behind, as it is non-volatile.
What is the difference between hot acidified potassium manganate 7 and potassium manganate 7?
The term "hot acidified potassium manganate 7" typically refers to a solution of potassium permanganate (KMnO4) in acid, while "potassium manganate 7" refers to the solid compound potassium permanganate itself. The acid in the hot solution helps to increase the reactivity of the potassium permanganate.
Which gas is given off when potassium permanganate is broken down?
Oxygen gas is given off when potassium permanganate is broken down. Potassium permanganate decomposes into manganese dioxide, potassium hydroxide, and oxygen gas when heated.
What will happen if small piece of crystall of potassium permaganate is dropped in a beaker filled with water and is heated?
When a small piece of potassium permanganate crystal is dropped into water and heated, it will dissolve and release potassium ions and permanganate ions into the solution. As the temperature increases, the rate of dissolution will also increase, leading to a faster dispersal of the ions. The purple color associated with potassium permanganate will be more pronounced as more of it dissolves.

What is the result by heating gently the pinch of KHSO4 and 2 drops of glycerol?
When gently heated, potassium bisulfate (KHSO4) reacts with glycerol to produce potassium sulfate, sulfuric acid, and water. This reaction generates heat, so it is exothermic.
Why potassium permanganate use in convection experiment?
Potassium permanganate is used in convection experiments as a visual tracer to observe the movement of fluid. When a small crystal of potassium permanganate is added to a liquid, it dissolves and spreads due to the fluid's movement, making it easier to visualize the convection current patterns.
What is the word equation for potassium permanganate when heated?
here is the rection... 2KMnO4 + 3H2SO4 = K2SO4 + 2MnSO4 + 3H2O + 2.5O2 (alkaline) and in other conditions... 6 KMnO4 + 9 H2SO4 → 6 MnSO4 + 3 K2SO4 + 9 H2O + 5 O3 The H2SO4/KMnO4 reaction can also produce the oily Mn2O7, which is unstable and can decompose explosively.
What happens when you heat potassium permanganate?
I'm not entirely sure but I'm pretty positive it turns black, thus releasing oxygen and this can be proved if the test tube containing the potassium manganate VII is connected to another test tube or bowl containig limewater because it will start to bubble and turn cloudy or milky.
Why heat oxalic acid before titrate with potassium permanganate?
Heating oxalic acid before titrating with potassium permanganate helps to accelerate the reaction and improve the accuracy of the titration by ensuring that the reaction proceeds quickly and completely. Heating also helps to break down any impurities or complexes that may interfere with the reaction, leading to more precise results.
What happens when K2cr2o7 is heated?
When potassium dichromate (K2Cr2O7) is heated, it decomposes into potassium chromate (K2CrO4) and oxygen gas (O2) is released. The color of the compound changes from orange to yellow as it loses oxygen atoms during the decomposition process.
