    Project Sample

    Analysis of Fruit Juices for Vitamin C Content

    The objective of this project is to analyze and compare the vitamin C content in different fruit juices using a simple and reliable titration method.

    Vitamin C, also known as ascorbic acid, is a water-soluble vitamin found in various fruits and vegetables. It is an essential nutrient required for the growth and repair of tissues in the body. The amount of vitamin C in fruit juices can vary significantly depending on factors such as fruit type, ripeness, storage conditions, and processing methods.

    The determination of vitamin C content in fruit juices can be achieved through a redox titration method using an oxidizing agent such as iodine (I₂). In this method, iodine reacts with ascorbic acid in the presence of an acid (like sulfuric acid) to produce dehydroascorbic acid and iodide ions:


    The end point of the titration is detected using a starch indicator, which changes color from blue-black to colorless as all the ascorbic acid in the juice sample reacts with iodine. The amount of iodine used in the titration is proportional to the amount of vitamin C present in the juice.


    • Fruit Juices: Different types of fruit juices (e.g., orange juice, lemon juice, grapefruit juice).
    • Standardized Iodine Solution: A standardized solution of iodine (I₂) for the titration.
    • Sulfuric Acid (H₂SO₄): To acidify the fruit juice samples for the reaction.
    • Starch Solution: A starch indicator solution for detecting the endpoint of the titration.
    • Burette and Pipette: To accurately measure and dispense the iodine solution and fruit juice samples.
    • Conical Flask: To hold the fruit juice samples during titration.
    • White Tile or Paper: To aid in visual detection of the endpoint color change.
    • Distilled Water: For dilution purposes and preparation of solutions.
    • Safety Equipment: Lab coat, gloves, and safety goggles for handling chemicals.

    Safety Considerations

    • Handle sulfuric acid and iodine solutions with care as they can cause skin irritation and damage.
    • Work in a well-ventilated area or fume hood to avoid inhaling vapors from chemicals.
    • Wear appropriate personal protective equipment (PPE) to ensure safety during the experiment.
