Why KMnO4 titration's are carried out only in the presence of dilute H2SO4?

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.

Which acid is better to use in the laboratory titrations H2SO4 or HCL why?
both of them are good , but i buffer H2SO4
Why sulfuric acid is used in redox titrations?
Dilute sulfuric acid H2SO4 is an indifferent acid to oxidising substances, while HCl (potential +1.36V) is a reductant and HNO3 (potential +0.96V) is an oxidant.
Chemical symbol for dilute sulphuric acid?
H2SO4 (dil) or H2SO4.H20.
What happens when sodium hydrogen carbonate reacts with dilute H2SO4?
2NaHCO3 + H2SO4 --> Na2SO4 + H2O(l) + CO2(g)
Is dilute sulphuric acid a compound?
Sulfuric acid itself is a compound with the formula H2SO4. However the word "dilute" means that the H2SO4 is dissolved in water, so it is a mixture.

What is the formula for dilute sulphuric acid?
Sulfphuric acid is the British spelling. The American spelling is sulfuric acid. Anyways, the formula is H2SO4.
Chemical formula for acid rain?
It is actually a mixture of very dilute H2SO4 and HNO3
How do you dilute a 10 M H2SO4 to 1M H2SO4?
Remember M1V1=M2V2, where M is molarity and V is volume. M1/M2=V2/V1, 10/1=v2/v1, For diluting the acid, we can add acid to water. So, assuming that 10M H2SO4 is having 1ml of water, we should add 1M of H2So4 to 10ml of water.
Concentration of H2SO4 titrations?
i dont know really......cos u have to be specific what volume is it in how many moles room temperature pressure precautions etc
