2MnO4- + 5H2O2 + 6H+ → 2Mn2+ + 5O2 + 8H2O
Permanganate is added to H2SO4 + H2O2 and is reduced because it is a better oxidising agent that H2O2
the purple MnO4 ion is used up and the solution fades almost to clear if the mix is right
2KMnO4 + H2SO4 ------- K2SO4 + Mn2O7 + H2O
O2 + Mn2O7(detonation by alcohol or striking it) ------- 2MnO2+ O3
The reaction would yield potassium sulfite and hydrogen permanganate.
H2SO3 + KMnO4 = H2MnO4 + K2SO3
This is an example of a double-displacement reaction.
To test for the presence of the peroxoborate borate anion in the solution.
Dihydrogen-Oxide
Solid potassium permanganate with hydrogen peroxide produces more oxygen which is not united with other elements than solid potassium permanganate with sulfuric acid H2O2.
Use an Oxidizer, such as acidified Hydrogen peroxide, acidified Potassium permanganate, Sulfuric acid (concentrated), etc.
Concentrated sulfuric acid reacts with Potassium permanganate to produce manganese VII oxide (commonly called manganese heptoxide), Mn2O7. Mn2O7 is a very strong oxidizer and will rapidly react with most organic compounds even at room temperature. In this case the reaction is able to produce light and sound even without contact with oxygen gas.
Hydrochloric acid being a very good reducing agent, will interfere with the titrations and be oxidised to chlorine by potassium permanganate. Hence sulfuric acid is used, and not HCl.
Potassium sulphate and water: H2SO4 + 2 KOH----------K2SO4 + 2H2O
Solid potassium permanganate with hydrogen peroxide produces more oxygen which is not united with other elements than solid potassium permanganate with sulfuric acid H2O2.
The reaction that produces more pure oxygen which is not united with other elements is solid potassium permanganate with hydrogen peroxide rather than solid potassium permanganate with sulfuric acid with H2O2.
It will change colour and become purple

Potassium sulphate and water: H2SO4 + 2 KOH----------K2SO4 + 2H2O
The permanganate ion, MnO4- purple in colour. The sulfuric acid is added to create acidic conditions. In acidic conditions, the MnO4- gets reduced to Mn2+ which is colourless. Therefore, judging by the colour change, we can figure out how much of the potassium permanganate has been used.
H2SO4 + K2CO3 --> K2SO4 + H2CO3 ...........................followed by H2CO3 --> H2O + CO2
Potassium Sulfate and water
Potassium sulfate = K2SO4
Actually there are two possibillities:K2SO4, potassium sulfate, when 1 mole sulfuric acid is added to 2 moles potassium hydroxide 2 KOH + H2SO4 ------> K2SO4 + 2 H2OorKHSO4, potassium hydrogen sulfate (-bisulfate), when 1 mole sulfuric acid is added to 1 mole potassium hydroxide 1 KOH + H2SO4 ------> KHSO4 + H2O
