Comparing vitamin C content in various beverages
Vitamin C, or ascorbic acid, takes part in a reversible reaction with iodine in solution. This can be used to compare vitamin C levels in various beverages.
Vitamin C, a water-soluble ion of ascorbic acid, is essential for normal growth, repair and development in humans. Unlike most other vertebrates, humans and some other primates are incapable of synthesizing their own vitamin C, with the result that it is a necessary requirement in our diet.
In this activity the relative vitamin C content of a range of juices and drinks will be examined using a technique known as titration. Titration involves adding one reactant to another until an end point, often indicated by a colour change, is reached.
