Why was HCL added for the titration f Vitamin C?
Hydrochloric acid (HCl) is added to the titration of vitamin C to acidify the solution and provide a suitable acidic medium for the reaction between vitamin C and iodine to occur. The acid helps in the oxidation of ascorbic acid (vitamin C) by iodine, which is essential for determining the vitamin C content accurately through titration.
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 oxalic acid is added before titration of vitamin c?
Oxalic acid is added before titration of vitamin C to ensure that any trace amounts of transition metal ions are complexed. These metal ions can interfere with the titration process, leading to inaccurate results. Oxalic acid helps to prevent this interference by forming complexes with the metal ions, allowing for a more accurate determination of the vitamin C content.
How does DCPIP titration determine vitamin C concentration?
DCPIP titration is a method used to determine vitamin C concentration by measuring the amount of DCPIP reduced by vitamin C. Vitamin C is a reducing agent and will reduce the blue dye DCPIP to a colorless compound. The concentration of vitamin C can be calculated based on the volume of DCPIP solution consumed during the titration.
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.

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.
What chemical would you use to confirm the presence of vitamin C?
To confirm the presence of vitamin C (ascorbic acid), you can use a solution of iodine. When iodine is added to a sample containing vitamin C, it will react and become decolorized, indicating the presence of vitamin C. This reaction occurs because vitamin C reduces iodine, turning it from a brownish color to clear. A titration method can also be utilized for quantitative analysis.
What is over-titration?
Over-titration refers to the process of adding too much titrant during a titration, resulting in an endpoint that goes beyond the equivalence point. This can lead to inaccurate results as the excess titrant can skew the calculations.
Can you suggest me a chemistry project regarding vitamin C eligible for class 12?
One possible project idea for a class 12 chemistry project on vitamin C could be to investigate the effect of different storage conditions (such as temperature, light exposure, or moisture) on the stability of vitamin C in various fruits or vegetables. You could analyze the vitamin C content using titration or spectrophotometric methods to determine how these storage conditions affect the degradation of vitamin C over time.
How much vitamins in Orange juice?
how much vitamin c is in an orange compared to concentrated Orange Juice withou added vitamin c
Is there vitamin C in frozen orange juice?
Yes. It can be an extra added ingredient, but oranges and all citrus fruits naturally contain Vitamin C.
If Vitamin C has been added to cranberry juice?
If Vitamin C is added to Cranberry juice, this must be listed on any nutritional list on the cranberry juice. It must also be included in the nutritional information.
