What type of indicator is used during potassium permanganate titration?
Ananda84
Usually there is no indicator needed in potassium permanganate titrations as there will be an excess of manganate ions in the conical flask, turning the solution from colourless to pale pink.

What is the purpose for using phenolphthalein for an acid base titration?
It's the colour indicator you watch for during the titration.
Why is important that the indicator is present in the solution during the course of titration?
the reason why a indicator is important in some titration is to show a change in the solution. for example as a solution runs from acidic to basic the indicator may turn a different color. but this is the reason why it is important inmost experiments.
What happens during an acidic base titration in the presents of an indication?
The indicator will change color as the pH changes.
Why is it that 2 or 3 drops of the indicator is added during titration of acid and base?
To see where the equivalent point is
In HCl and NaOH titration which indicator is used?
Phenolphthalein indicates red for acids and blue for bases.

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.

Why double indicator is used during the titration of water to find alkalinity of water sample?
A double indicator is used to find the alkalinity of the water sample to prevent errors.
Reaction of formaldehyde with potassium permanganate?
Benzaldehyde reacts with pottasium permanganate to generate benzoic acid (oxidation). Basic cnditions are required for the action of pottasium permanganate so sodium carbonate is used. But this gives sodium salt of benzoic acid which is soluble in water. To retrieve benzoic acid which is insoluble in water we use HCl.
What is an indicator blank?
During an experiment for chemistry, if an indicator will not work due to the lack of a reactant, the reactant can be added. You must then compensate for the added amount by creating a solution of the indicator and the the same amount of the reactant. The volume required in the blank titration must then be subtracted from the other results to obtain quality results. This is an indicator blank and how it is used.
What is the endpoint of a titration?
during a titration when a titrant completely furnished the sample then this is the end point of titration.
What is the reason of heating solution during redox titration?
This is far to be a rule for this titration.
Why is a small amount of indicator added during titration?
An indicator shows when we have added just enough of the second reagent to react with the first. If you mean why do we add only a small amount of indicator, it is to keep the answer accurate. Some of the reagent is used changing the indicator so the answer is always slightly bigger than perfection, and the more indicator you add, the larger the error.
