WebPlace single drops of iodine solution in rows on the tile. Iodine solution is orange-brown. Label a test tube with the pH to be tested. Use the syringe to place 2cm 3 of amylase in the test tube. Equal volume and concentration of enzyme should be used so these variables are controlled and the effect of changing pH can be measured. WebIdeally the reaction should take about 60 seconds at this pH: this is the usual optimum for amylase (see note 1). If the reaction is too fast, either reduce the enzyme volume or …

WebPhenolphthalein is an indicator that is pink in alkaline solutions of about pH10. When the pH drops below pH 8.3 phenolphthalein goes colourless. Here, an alkaline solution of milk, lipase and phenolphthalein will change from pink to colourless as the fat in milk is broken down to form fatty acids (and glycerol) thus reducing the pH to below 8.3.
