Why is there colour change in the reaction between oxalic acid and potassium permanganate?

The dark purple color of permanganate fades because during the reaction permanganate is reduced to manganese cations and water. The other reactants and products are not strongly colored.

Write the chemical reaction between cyclopentene and potassium permanganate?
cyclopentene reaction with potassium permanganate. If cyclohexene gives a diacid (two acid groups in a opened ring), I think that is should yield a pentane with two acid groups, one in each end....it could give more products like CO2 and H2O, by breaking the bonds, you could get a lot of compounds, depending which bonds could break.....
Is the reaction between magnesium nitrate and potassium chromate chemical or physical what is the chemical equation for this reaction?
The reaction between magnesium nitrate and potassium chromate is a chemical change. 2KOH(aq) + Mg(NO3)2(aq) --> 2KNO2(aq) + Mg(OH)2(s)
What is the reaction of Potassium permanganate and salicylic acid?
ofcourse salicylic acid would react with Hot, acidic Potassium permanganate because it has a phenol group in its structure. and based in our chem, this kind of reagent is used to test the presence of phenol. to prove, or to give you a visible result, your finished product must change its color from purple to dark brown precipitate, this means that salicylic acid is already oxidized by the strong oxidizing agent.. *kuha mo?? anong hindi nagreact. imbento !
What chemical's solubility is most affected by change in temperature potassium nitrate or salt?
Unlike salt, potassium nitrate's chemical solubility is most affected by a change in temperature. Potassium nitrate is a chemical compound.
When naming a compound containing potassium and chlorine change the suffix of the anion name to?
potassium chloride
Characteristics of reaction of lemon juice and potassium permanganate?
In this i think change of colour takes place
Why is the reaction between glycerol and potassium permanganate irreversible?
The reaction between glycerol and potassium permanganate is irreversible because it involves a complete change in the molecular structure of the reactants. Glycerol, an alcohol compound, is oxidized by potassium permanganate, resulting in the formation of different products, such as carbon dioxide, water, and manganese dioxide. Once these new products are formed, it is difficult to reverse the reaction and reform the original reactants.
Why colour of ethanol changes when mix with potassium permanganate?
The purple color of the KMnO4 will change to a muddy brown.

Chemical reaction for potassium nitride?
It reacts with water to produce toxic Ammonia
Is burning potassium permanganate a chemical change?
yes definetly,if you burn KMnO4 it change to Mno2,and some other product.
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 happen if the potassium permanganate solution drop to the water and add of concentrated sulfuric acid?
It will change colour and become purple
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

Is Potassium chloride decomposes to potassium chloride and oxygen gas is a physical or chemical change?
Chemical
Is potassium cloride dissolving in water a chemical change?
Potassium metal does not dissolve in water, it is so reactive that it rips water molecules apart releasing hydrogen gas and combining with the remaining hydroxyl group to form potassium hydroxide (potash lye) which then dissolves in the water. This chemical reaction releases so much heat that it ignites the hydrogen gas that was emitted which produces water vapor/steam and a light purple flame (caused by excited potassium ions).
