What happens when potassium permanganate and glycerol is heated?

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.

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.
Why heat oxalic acid before titrate with potassium permanganate?
The oxalic acid is heated to icrease the rate of reaction which is very slow at room temperature
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.
When heated potassium nitrate decomposes to form?
When heated potassium nitrate decomposes to form :K O^2NO
Does potassium iodide melt easily when heated?
Potassium iodide, like salts in general, has a high melting point. It does not melt easily when heated.

Why potassium permanganate use in convection experiment?
simply because the chemical gives a very dark/strong purple color. You'll be able to see where the convection currents take the chemical in stagnant water when the medium (water) is heated...

What will happen if small piece of crystall of potassium permaganate is dropped in a beaker filled with water and is heated?
The water turns purple, and gets hotter. And what happens to the beaker? Depending on what it is made of, and the temperature to which it is heated, it might melt.
Which element gives off a violet vapor when heated?
Potassium (also named Kalium), symbol K.
What happens when heating potassium chlorate?
Potassium nitrate also known as salt petre is a chemical compound with the formula KNO3 which on heating to above 560 °C decomposes into potassium nitrite, and oxygen.given by the following chemical equation-2 KNO3 → 2 KNO2 + O2
What is the balanced equation for heated potassium chlorate decomposing into oxygen and potassium chloride?
2KClO3 --> 2KCl + 3O2
The result of Acrolein Test?
Acrolein test is a test for the presence ofglycerin or fats. A sample is heated with potassium bisulfate, and acrolein is released if the test is positive.[8] When a fat is heated strongly in the presence of a dehydrating agent such asKHSO4, the glycerol portion of the molecule is dehydrated to form the unsaturated aldehyde, acrolein (CH2=CH-CHO), which has the peculiar odor of burnt grease.
What happens to matter when heated?
When matter is heated it will expand
