potassium permanganate vs glycerine whats going to happen
When potassium permanganate is mixed with glycerine, a highly exothermic reaction occurs. The reaction can be violent and can result in the formation of fire. This is because glycerine is a reducing agent, and when it comes into contact with potassium permanganate, it causes oxidation of the glycerine and reduction of the potassium permanganate.
The reaction between potassium permanganate and glycerine starts slowly but rapidly accelerates. Initially, there may be the formation of small sparks or flames due to the reaction, followed by a release of heat and smoke. As the reaction progresses, a fire can ignite, with the possibility of an explosion if the reactants are confined.
It is important to note that this reaction should not be attempted by individuals without proper training and safety precautions. Mixing potassium permanganate with glycerine can be extremely dangerous and should only be performed in controlled laboratory settings by experienced professionals.
so was there a physical change or a chemical change
The reaction between potassium permanganate and glycerine involves a chemical change. In this reaction, the molecules of potassium permanganate (KMnO4) and glycerine (C3H8O3) undergo a chemical reaction, resulting in the formation of different compounds.
During the reaction, the potassium permanganate is reduced while the glycerine is oxidized. This exchange of electrons between the reactants leads to the formation of new compounds and the release of heat and light, indicating a chemical change has taken place.
Therefore, the reaction between potassium permanganate and glycerine is an example of a chemical change rather than a physical change.
what is cassing the change
The chemical change that occurs when potassium permanganate is mixed with glycerine is primarily due to their chemical properties and the redox reaction that takes place.
Potassium permanganate (KMnO4) is a strong oxidizing agent. It readily donates oxygen atoms, which results in the oxidation of other compounds. In this reaction, potassium permanganate accepts electrons from the glycerine molecules.
Glycerine (C3H8O3), on the other hand, is a reducing agent. It has the ability to donate electrons to oxidizing agents, leading to its oxidation.
When these two substances are mixed, the oxygen atoms from potassium permanganate react with the carbon and hydrogen atoms of glycerine, breaking and forming new chemical bonds. This process results in the oxidation of glycerine and reduction of potassium permanganate, causing a release of heat, light, and potentially flames.
In summary, the change that occurs when potassium permanganate is mixed with glycerine is caused by the redox reaction between their chemical properties, specifically the oxidizing properties of potassium permanganate and the reducing properties of glycerine.
When potassium permanganate (KMnO4) comes into contact with glycerine, a redox reaction takes place. This reaction can be quite vigorous and can result in an exothermic reaction, meaning it produces heat.
To understand what happens, let's break it down into the reaction equation and steps:
1. The reaction equation:
2 KMnO4 + 3 C3H8O3 -> 2 MnO2 + 2 KOH + 5 H2O + 3 CO2
2. Initial step:
KMnO4 dissociates in water into the manganese (Mn) ion (Mn^2+) and the permanganate ion (MnO4^-). Glycerine (C3H8O3) is a triol compound.
3. Redox reaction:
The MnO4^- ion acts as an oxidizing agent, while the glycerine acts as a reducing agent. The permanganate ion can easily accept electrons, while glycerine can donate them.
4. Resulting products:
The reaction yields brown/black-colored manganese dioxide (MnO2), which is an insoluble solid. Additionally, potassium hydroxide (KOH), water (H2O), and carbon dioxide (CO2) are formed.
It is important to note that this reaction is highly exothermic and can generate a substantial amount of heat, which can lead to a flame or, in certain situations, an explosive reaction. Therefore, this reaction should only be performed by individuals with proper knowledge and expertise in chemistry, using appropriate safety precautions and under controlled conditions.
