Plan Aim: The aim of this taste is to identify the optimal pH for which the enzyme, amylase, full treatment best at. Hypothesis: I prophesy that enzyme bodily process will decrease if it steers away from 6-8 pH as this is the optimum pH start out for which the enzyme amylase works best. Variables: Dependant Variables: The time it takes the enzyme to react. maintain Variables: The summate of starch prepare The metre of enzyme solution The amount of Iodine solution The amount of water in ML The time taken for the reaction. autarkical Variables: The range of pH, between 6-8 pH. Method: 1. Firstly, coif the buffer viva voce contraceptives into a test-tube containing 20 ml of water (at room temperature). 2. at a time the buffer tablet has dissolved into the water, add 10 ml of starch solution. 3. later the starch solution has been added, add 10 ml of enzyme solu tion to the current solution, simultaneously start the timer and record at 1 minute intervals. 4. In addition, posture iodine in the dropping tile in slash to identify if starch is currently present. 5. Repeat each experiment 3 times. Equipment: 1. drop Tile 2. Pipette 3. Test organ pipe 4. Starch ancestor 5. Iodine Solution 6. Enzyme Solution 7. Beaker(s) 8. water 9. Measuring Cylinder (ml) 10. oecumenical Indicator 11.
