DISCUSSION:

 This experiment is carried out to study the Vitamin C content in various fruit

 juices, be them the bottled or the fresh ones. The smaller volume of fruit juice

needed to decolorize the blue DCPIP solution, the hiher is the Vitamin C content in

the fruit. !iher Vitamin C content may be found in citrus fruits such as lemon and

orane. Citrus fruits are acidic" therefore this may explain #hy the Vitamin C

content in citrus fruits is hiher compared to others. The smaller volume of fruit

 juice needed to decolorize the DCPIP solution means that the DCPIP solution is

reduced at a faster rate" thus it can be assumed that the concentration of !$ ions

from the ascorbic acid in the fruit is hiher.
