Question:We're doing a titration involving sulfuric acid, potassium permanganate, and hydrogen peroxide. One of the questions is "write the balanced redox reaction". However, first I have to write the balanced chemical equation, but I have no idea how to find the product of the reaction (before splitting into ionic form). From what I hear, this 5H2O2 + 2KMnO4 +4H2SO4 -->2KHSO4 + 2MnSO4 + 5O2 +8H2O
is the balance chemical equation, but I don't understand how the Manganese can split off from the oxygen and attach to sulfate. I also don't understand why sulfuric acid become KHSO4.
Answers:here is the correct equation nett equation
2MnO4- +5H2O2 + 6H+ = 2Mn2++ 5O2 + 8H2O
here are the hal equations
MnO4-(aq) + 8H+(aq) + 5e-==> Mn2+(aq) + 4H2O(l)
H2O2(aq ==> O2(g) +2H+(aq) + 2e-
to get the correct nett equation multiply1 by 2 and 2 by 5 the add
balance the H's on both side .. presto !!
Question:5 H2O2(aq) + 2 KMnO4(aq) + 3 H2SO4(aq) 5 O2(g) + 2 MnSO4(aq) + K2SO4(aq) + 8 H2O(l)
It requires 40.9 mL of 0.200 M KMnO4 to titrate 20.0 g of the solution of hydrogen peroxide. What is the mass percentage of H2O2 in the solution?
Answers:Moles KMnO4 = 0.0409 L x 0.200 =0.00818
Moles H2O2 = 0.00818 x 5 / 2 =0.0205
Mass H2O2 = 0.0205 mol x 34.0148 g/mol =0.697 g
% = 0.697 x 100 / 20.0 =3.49

Question:Some of them are:
1. Oxalic Acid
2. Hydrogen Peroxide & Acetic Acid
Can i get some more inputs and chemicals which neutralize KMnO4?
Which process works best and how do they act (if possible)? We use KMnO4 in the textile industry. We spray KMnO4 on the denim fabric to get different effects. After the process is completed, we have to neutralize this KMnO4. Which chemicals / chemical combination can work out best? We can't use sulphur compounds since it will leave a smell on the fabric.
Answers:If you can give precise situation where KMnO4 has to be removed then a precise answer can be given. In this case some assumptions have to be made to answer the question.
I presume that you need a procedure to remove unreacted / excess of KMnO4 from a reaction mixtrure. Or some KMnO4 is present where it was not needed and it has to be removed. or some other similar situation.
KMnO4 is an oxidising agent and give out oxugen in acidic, alkaline or even in neutral medium. Therefore to neutrlize (remove ) some reducing agent will be needed. Some of the suggested reducing agents are oxalic acid, sodium oxalate, SO2. sodium suphite, sodium bisulphite, H2O2 ( can also act as a reducing agent). While using oxalic acid or sodium oxalate or sodium slphite or bisulphite an acidic medium will be needed.
2 KMnO4 + 3 H2SO4 ----------> K2SO4 + 2 MnSO4 + 3 H2O + 5 [O]
The oxgen evolved can oxidised the reducing agents to corresponding oxidised product.
5 C2O4H2 + 5 [ O ] ---------> 10 CO2 + 5 H2O
SO2 + H2O + [O] -------------> H2SO4
H2O2 + [O] ----------> H2O + O2
Many other reducing agents can be used.
Decomposition of Hydrogen peroxide by Potassium permanganate :IMPORTANT: All content here meant to be Educational,None of the above experiment should be repeated on your own. It is a reaction between 50% Hydrogen peroxide (H2O2) and Potassium permanganate (KMnO4) . It is a very vigorous reaction which steam (H2O) and Oxygen (O2) are the desired products, side products include Manganese(IV) oxide (MnO2) and trace amount of Potassium compound.

chemical reaction Hydrogen peroxide + potassium permanganate :Hydrogen peroxide and potassium permanganate in a nice chemical reaction I only used low concentrated chemicals. If some one use high concentrated chemicals it would also work faster. But this is dangerous. I am careful with chemicals. This reaktion can by used in rockets and both chemicals are caustic. If the chemicals are too high concentrated it could by like an explosion. Not funny if you be a few steps from ther. Wasserstoffperoxid und Kaliumpermanganat bei der chemischen Reaktion.
