Balanced equation for oxalic acid and potassium permanganate?
2co +o2 ---> 2co2
Why is phenolphthalein indicator used in the titration of oxalic acid against sodium hydroxide?
Yes. Phenolphthalein can be used as an indicator for the titration of a weak acid (oxalic acid) against strong base (sodium hydroxide).
Why heat oxalic acid before titrate with potassium permanganate?
The oxalic acid is heated to icrease the rate of reaction which is very slow at room temperature
What indicator can you choose for the titration of oxalic acid with sodium hydroxide?
Phenolphthalein, because NaOH is a strong base.
What is the reaction between potassium permanganate and sulphuric acid and oxalic acid?
Potassium Permanganate (KMnO4) reacts with Sulphuric acid (H2SO4) to produce Manganese Heptoxide (MnO7), water (H20) and Potassium Hydrogen Sulphate (KHSO4)2. The reactive species produced is Manganese Heptoxide (which is a very powerful oxidiser). The Manganese Heptoxide will oxidise the Oxalic acid (COOH)2 to Carbon dioxide (CO2).

Why do you have to heat up the solution of oxalic acid after adding sulphuric acid for the titration with permanganate?
To act as a catalyst
Why is phenolphthalein indicator used in the titration of oxalic acid against sodium hydroxide?
Yes. Phenolphthalein can be used as an indicator for the titration of a weak acid (oxalic acid) against strong base (sodium hydroxide).
How is oxalic acid vs NaOH titration different from oxalic acid vs potassium permegnate titration?
The former is a acid base neutralisation reaction whereas the latter is a redox reaction.

Phenolphthalein, because NaOH is a strong base.
Why 2N sulphuric acid is used in oxalic acid estimation?
This titration is based on the neutralization reaction between oxalic acid and sulfuric acid; a pH indicator is used.
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.

Which indicator is used in titration of oxalic acid with HCl?
Both HCl and oxalic acid are acids. Therefore, since there is no alkali present, these compounds do not undergo neutralization. So there is no suitable indicators for the addition of these two reagents.
Why oxalic acid is heated before titration with KMnO4?
Oxalic acid is generally warmed slightly because it is not completely soluble and heat helps this. It aids in accuracy of the titration.
Why oxalic acid is acidified before titration?
for medium produce
