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.
What happens when hexene reacts with cold neutral and dilute potassium dichromate?
One would expect that the reaction between an alkene and cold, dilute potassium dichromate is an oxidation to a bifunctional alcohol at the carbons in the double bond. The result is also called a vincinal diol or a glycol. The reaction should be similar to the reaction of an alkene with cold, dilute potassium permangante, however, dichromate is a milder oxidizing agent and may not be as effective. The mechanism for this reaction involves the formation of an intermediete 'ester' with the metal at the carbons of the double bond, breaking the double bond. The it can be shown that the resonance structure of the intermediete complex transfers electron density to the ester linkage and protonates from water at both of the ester sites completing the oxidation.
What happens when potassium is allowed to burn in bromine vapour?
When potassium is allowed to burn in bromine vapor, a vigorous reaction occurs, resulting in the formation of potassium bromide. The reaction produces a bright light and heat. Potassium bromide is a stable, white crystalline compound.
What happens when potassium hydroxide and hydrolic acid mix?
When potassium hydroxide and hydrochloric acid mix, a neutralization reaction occurs, producing potassium chloride (KCl) and water (H2O). This reaction is exothermic, meaning it releases heat. Potassium chloride is a salt that is soluble in water.
What happens if oxygen mixed with potassium?
When oxygen is mixed with potassium, it can react vigorously, sometimes even explosively. This reaction forms potassium oxide, which is a white powder, and releases a large amount of heat. This kind of reaction is highly exothermic and needs to be handled with caution.
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.

What happens when sulfur reacts with potassium?
When sulfur reacts with potassium, they form potassium sulfide. This reaction involves the transfer of electrons from potassium to sulfur, resulting in the formation of ionic bonds. The reaction is exothermic, meaning it releases energy in the form of heat.
What happens when it is put in water potassium?
Potassium metal will react violently with water to form KOH and hydrogen gas. Due to the heat released by the reaction - the hydrogen gas will ignite. So: placing potassium in water will cause a fire!
What happens if you heat potassium SORBATE?
When potassium sorbate is heated, it may decompose into potassium carbonate, carbon dioxide, and water vapor. This decomposition process can lead to the release of carbon dioxide gas and create a foul odor. It is important to heat potassium sorbate cautiously and in a well-ventilated area to prevent any potential hazards.
Does potassium vigorously react with acid and also conducts heat?
Potassium does indeed react vigorously with acid and also conducts heat well.
What happens when potassium hydroxide and hydrolic acid mix?
When potassium hydroxide and hydrochloric acid mix, a neutralization reaction occurs, producing potassium chloride (KCl) and water (H2O). This reaction is exothermic, meaning it releases heat. Potassium chloride is a salt that is soluble in water.
What is the effect of heat on the nitrate of potassium?
it decomposes into potassium nitrite and oxygen.
What happens if oxygen mixed with potassium?
When oxygen is mixed with potassium, it can react vigorously, sometimes even explosively. This reaction forms potassium oxide, which is a white powder, and releases a large amount of heat. This kind of reaction is highly exothermic and needs to be handled with caution.
What happens when the two hazardous elements potassium and chlorine are combined?
When potassium and chlorine are combined, they form potassium chloride, a compound commonly used as a salt substitute. This reaction is highly exothermic, meaning it releases a significant amount of heat energy. Potassium chloride is stable and non-hazardous when handled properly.
