Why is acetic acid added to vitamin C in a titration reaction with KI and N bromosuccinimide?
Acetic acid is added in the titration reaction to provide the acidic conditions necessary for the reaction between KI and N-bromosuccinimide to occur effectively. The acidic medium helps to convert KI to iodine, which can then react with N-bromosuccinimide. This reaction is commonly used to determine the vitamin C content in a solution.

WHY IT IS NECESSARY TO DILUTE THE VINEGAR TITRATION WITH O.1 m naoh?
Diluting the vinegar in a titration with 0.1 M NaOH is necessary to ensure that the reaction occurs within a measurable and interpretable range. Vinegar, being an acetic acid solution, can have a high concentration that may lead to overshooting the endpoint if not diluted. This dilution allows for a more accurate determination of the acetic acid concentration by providing a clearer endpoint and reducing the potential for errors in measurement. Additionally, it helps in achieving a more gradual reaction, improving the precision of the titration results.
What is the reaction when zinc acetic anhydride and glacial acetic acid are combine?
When zinc is reacted with acetic anhydride and glacial acetic acid, a complex called zinc acetate is formed. The reaction typically involves the displacement of acetic anhydride by acetic acid to form zinc acetate. The overall reaction is a redox reaction where zinc is oxidized and acetic anhydride is reduced.
Is aspirin synthesis an esterification reaction?
No, aspirin synthesis is not an esterification reaction. It involves the reaction of salicylic acid with acetic anhydride to form acetylsalicylic acid (aspirin) and acetic acid through an acetylation reaction. Esterification typically involves the reaction of an alcohol with a carboxylic acid to form an ester.
In the preparation of aspirin water is added to the reaction flask Why?
The formation of aspirin will proceed faster if acetic anhydride is used in place of acetic acid. However, acetic anhydride will hydrolyze in the presence of water to form acetic acid, slowing down the reaction.
Why doesn't adding water to a vinegar sample prior to titration affect the calculated molarity?
That is a question that confuses many. It is because the water is not acidic and therefore does not affect a colour change. You have a known volume of vinegar when starting the experiment.
Why is acetic acid added for the titration of vitamin C?
Acetic acid is added to the titration of vitamin C to create an acidic environment, which helps to prevent the oxidation of vitamin C during the titration process. This ensures that the vitamin C being titrated remains stable and accurate results can be obtained.
Why is acetic acid needed for the titration of vitamin C?
Acetic acid is needed in the titration of vitamin C to create an acidic environment that stabilizes the ascorbic acid molecule, preventing oxidation. This ensures accurate results during the titration process by maintaining the stability of the vitamin C solution.
What is the role of sodium bicarbonate in a redox reaction?
With an acid (commonly used: acetic) CO2 is formed so oxygen from air is excluded in the oxidimetric titration reaction. It otherwise might interfere with the titrant.

Can the acidity due to acetic be found out by the titration procedure?
N cannot be found by the titration procedure because the acetic acid is very weak acid and cannot be appear completely during the tit ration procedure
How many titratable protons are in ch3cooh?
There is one titratable proton in acetic acid (CH3COOH). It is the proton on the carboxyl group that can be donated in an acid-base reaction during titration.

Does acetic acid contain vitamin?
No, not at all.
What is the use of buffer in EDTA titration?
In EDTA titration, a buffer solution is used to maintain a constant pH level throughout the titration process. This helps to ensure accurate and reproducible results by preventing any variations in the reaction due to changes in pH. The buffer solution typically contains an acidic species (such as acetic acid) and its conjugate base (such as sodium acetate) to maintain a stable pH around the optimal range for the reaction.
Why acetic acid is heated before titration with potassium permagnate?
Acetic acid is too weak an acid to provide the desired acidity in the solution, The reaction at room temperature is slow because of the equilibrium nature of this reaction. CO2 is highly soluble in water and thus heating removes all dissolved carbondioxide out of the solution driving the reaction in forward direction. 2KMnO4 + 5 H2C2O4 + 3H2SO4 = 2MnSO4 + K2SO4 + 10 CO2 + 8H2O 2MnO4¯ + 10 C2O42¯+ 16H+ = 2Mn2+ + 10 CO2 + 8H2O at low temperature, the reduction of permanganate may not be complete producing Mn(III) (in the form [Mn(C2O4)3]3-).This complex however breaks on heating and hence reaction proceeds smoothly.
What is the reaction between hydrogen peroxide and acetic acid?
The reaction between hydrogen peroxide and acetic acid produces water and oxygen gas as products. This reaction is known as a decomposition reaction.
