DEDICATION We wish to express my sincere appreciation to my Chemistry teacher, Puan Subadhra A/P Andikot Raman for her keen and endless guidance, encouragement, critics and inspiration till the success and completion of this work. Not only that, we will not forget the help she gave us in solving the problems we encountered throughout the research. We also want to show our gratitude to the lab assistants and staffs in the school for giving the guidance to prepared the materials. Besides, we have to appreciated the cooperation of the group members who are work together to completed the experiment.

Abstract
The goal of the analysis is to know the content of ascorbic acid (vitamin C) in the three types of fruit juice, A (pineapple juice), B (Orange juice) and C (mango juice). The lower the volume of fruit juice required to decolourise the 2,6-dichlorophenolindophenol (DCPIP) , the higher the content of vitamin c (ascorbic acid) in the labelled juices, A, B and C. The method used to determine the content of vitamin C is by using titration method. From the results, we concluded that the different types of fruit juice of the same brand do contain the same content of vitamin C.
