Ascorbic acid is titrated by redox titration because it readily undergoes oxidation. The ascorbic acid molecule itself acts as a reducing agent that can be oxidized to form dehydroascorbic acid. The endpoint of the titration is reached when all the ascorbic acid has been oxidized.

Difference between acid base titration and redox titration?
In acid-base titration, the reaction involves the transfer of protons between the acid and base, with the endpoint usually determined by a pH indicator. Redox titration, on the other hand, involves the transfer of electrons between the oxidizing and reducing agents, with the endpoint typically determined by a change in color or potential. Acid-base titrations are used to determine the concentration of acids or bases, while redox titrations are to determine the concentration of oxidizing or reducing agents.
Why sulfuric acid is used in Redox titration instead of HNO3?
Sulfuric acid is commonly used in redox titrations because it is a strong acid and does not participate in the redox reactions. Nitric acid (HNO3) can act as an oxidizing agent itself, which can interfere with the redox titration process by introducing additional reactions.
What happen when ascorbic acid is treated with hydrochloric acid?
When ascorbic acid is treated with hydrochloric acid, it undergoes a redox reaction and is oxidized to form dehydroascorbic acid. This reaction reduces the ascorbic acid to lose its vitamin C activity.
What are the method of titration?
The methods of titration include acid-base titration, redox titration, and complexometric titration. Acid-base titration involves the reaction between an acid and a base to determine the concentration of one of the reactants. Redox titration involves oxidation-reduction reactions to determine the concentration of a substance. Complexometric titration involves the formation of a complex between a metal ion and a complexing agent to determine the concentration of the metal ion.
How many tipes of titration?
There are various types of titration. It is dependent on the conditions used and the reactants and desired products. Some of them are acid-base titration, redox titration, colorimetric titration and thermometric titration.

Types of conductometric titration?
Some types of conductometric titrations include acid-base titrations, redox titrations, and precipitation titrations. Conductometric titration involves measuring the change in electrical conductivity as reactants are titrated against each other until an equivalence point is reached.
Can oxalic acid be titrated by HCl?
Yes, oxalic acid can be titrated by HCl because oxalic acid is a diprotic acid and can react with HCl in a simple acid-base reaction. The titration involves determining the volume of acid required to neutralize the oxalic acid solution, which can be used to calculate the concentration of oxalic acid.
What factors influence the pH at the equivalence point in a strong-strong titration?
The factors that influence the pH at the equivalence point in a strong-strong titration are the strength of the acid and base being titrated, the concentration of the acid and base, and the volume of the acid and base used in the titration.
Why sulphuric acid is used in redox titrations?
Sulfuric acid is commonly used in redox titrations for several reasons: it provides a suitable acidic environment for the reaction to occur, it can help prevent interference from other substances in the sample, and it can also help stabilize the oxidation state of certain species being titrated. Additionally, sulfuric acid is a strong acid, which ensures that the pH of the solution remains constant during the titration process.
Why in acid base titration acid is always taken in burette?
In an acid-base titration, the substance being titrated is typically less abundant or more prone to contamination than the titrant. By placing the acid in the burette and titrating it with a base, the volume of base required to reach the equivalence point can be precisely measured and controlled. This setup allows for accurate determination of the concentration of the acid being titrated.
Which is the end point in acid base titration?
The end point in an acid-base titration is the point at which an indicator changes color and signifies that equivalence has been reached between the acid and base being titrated. This is when the amount of acid and base are in stoichiometric proportions.
What are different types of titration?
There are several types of titration techniques, including acid-base titration (determining the concentration of an acid or base), redox titration (determining the concentration of oxidizing or reducing agents), complexometric titration (determining the metal ion concentration using a complexing agent), and precipitation titration (determining the concentration of a dissolved substance by precipitating it).
