How can we test for vitamin C?

Vitamin C can be tested using a simple chemical reaction known as the iodine titration method. In this test, a solution of vitamin C is mixed with an iodine solution. Vitamin C is an antioxidant, so it reacts with iodine and reduces it to iodide ions. The reaction continues until all the vitamin C is consumed, and the iodine excess gives a blue-black color to the solution. By measuring the amount of iodine used, we can determine the concentration of vitamin C in the sample. Another common method is using a colorimetric assay, where a reagent containing a dye that changes color in the presence of vitamin C is added to the sample. The intensity of the color change is proportional to the amount of vitamin C present.
