What will happen if hydrochloric acid is used instead of sulfuric acid in permanganometric titrations?
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.
Why is nitric acid not often used as a standard solution for neutralization titrations?
The usual primary standard for acid-base titration is sulfuric acid. Nitric acid tends to lose NO2 by volatilization and HCl is also more volatile.
Why is potassium permanganate used for most titrations?
because it is both strong oxidising and reducing agent
Example two acids used in the laboratory?
Nitric acid, hydrochloric acid.
What type of indicator is used during potassium permanganate titration?
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.

Conclusion for the determination of iron by permanganate?
The conclusion for the determination of iron by permanganate is that oxidation of iron is one of the most popular titrations. All permanganate titrations, when used as a titrant, should use different techniques to read volume of liquid in the burette.

because it is both strong oxidising and reducing agent
Is nitric acid the same as sulfuric acid?
nitric acid be used insted of hypophrosphous acid
Example two acids used in the laboratory?
Nitric acid, hydrochloric acid.

Are fertilisers nitric acid?
No. Nitric acid is used to produce the ammonium nitrate which goes into fertilizers.
What acid is used in calcium nitrate?
nitric acid
What is the role for nitric acid?
The role of nitric acid in anal sex? To destroy the innards of the idiot who used it.
Is nitric acid a tear gas?
No, it is FAR TO toxic to be used as such. Nitric acid is having molecular formula HNO3
The purpose of an indicator in a titration experiment?
The indicator is used to measure the end point of titration. Methyl red and phenolphthalein are frequently used indicators in acid-base titration. Potassium permanganate can used as a self indicator in redox titrations where applicable.
