Investigating the affect of yeast concentration on the rate of reaction Aim: In this experiment I will investigate how the concentration of yeast affects the rate of reaction. Fair test: I will make sure it is a fair test by abiding to the list of measurements, I will use: 25ml of glucose and yeast solution 10% concentration of glucose - Yeast concentration varies Temperature at 37 C Also I will wash every piece apparatus that needs to be re-used thoroughly Apparatus: In my experiment I will need a variety of apparatus, I will need: 6 boiling tubes 1 delivery tube A water bath The specified amounts of glucose and yeast 5 pipettes A small amount of water A measuring cylinder A stop-clock I will set the experiment up as shown: Method: I will set up the apparatus as shown. With water in one test tube and the other one containing 25ml of the yeast and glucose solution, also the water bath will be set at 37 C...
