(a) She uses this apparatus. pH11 alkali pH9 alkali pH7 water pH5 acid pH3 acid starch solution amylase solution stopwatch measuring cylinder iodine (i) At which pH do you predict the enzyme amylase will work best? [1] The enzyme amylase breaks down starch in the mouth. The pH in the mouth is 7. Iodine solution is very dark blue when there is starch. Iodine solution is yellow when there is no starch.
