Effect of Heat on Vitamin C Objective: - To determine whether the concentration of Vitamin C in a fruit juice changes upon heating at a constant temperature for different periods of time. - To investigate how the trend goes (whether the concentration of Vitamin C increases or decreases) if the amount of Vitamin C does change. Theory: - Hypothesis: The concentration of Vitamin C in the fruit juice changes and decreases upon heatingat a constant temperature for increasing periods of time

Title : The Vitamin C content of fruit juice Aim : To investigate the vitamin C content of fruit juice. Introduction : [2]Vitamin C‚ also known as the ascorbic acid or the L-ascorbate‚ is required for the growth and repair of tissues in all parts of our body. It is necessary to form collagen‚ an important protein used to make skin‚ scar tissue‚ tendons‚ ligaments‚ and blood vessels. Vitamin C is essential for the healing of wounds as well as for the repair and maintenance of cartilage‚ bones

: The Vitamin C Content of Fruit Juices Lecturer : Madam Rita Rohaizah binti Sohari TITLE: THE VITAMIN C CONTENT OF FRUIT JUICES INTRODUCTION Vitamin C which is also known as ascorbic acid is an essential nutrient for human. It is a water-soluble vitamin that is necessary for normal growth and development. Water-soluble vitamins dissolve in water. Leftover amounts of the vitamin leave the body through the urine. That means a continuous supply of vitamin is needed in daily

Experiment 1: Calibration of Volumetric Glassware Introduction: Volumetric glassware is used to accurately measure volumes. Despite all of the tools and instruments available for the use of measuring values of various data‚ it is impossible to measure the true value of anything. This experiment is intended to develop a person’s capacity to handle volumetric glassware. One must understand how to handle volumetric glassware to acquire the best possible data from the equipment used in lab. Although
