To look at the effect of temperature of juice on the content of Vitamin C. Variables

Self-employed: Temperature of orange juice – 25°C, 50°C, 100°C Dependent: Articles of Vitamin C recorded by the range of Iodine drops Controlled: Quantity of orange colored juice – 2mL assess using a 25mL pipette Managed: Amount of starch option – 2mL measure utilizing a 25mL pipette Controlled: Amount of hydrochloric acid 1M – two drops via a dropper bottle Manipulated: Amount of distilled normal water – 4mL measure by using a 25mL pipette Controlled: Large molar concentration of hydrochloric acid (HCl) – 1M handled using the same dropper bottle of HCl each time Speculation

As the temperature of the juice boosts the content of Vitamin C will decrease. Materials
