When I did my experiment I had 4 different pH buffer solutions and i put starch solution and enzyme in with iodine to indicate when there was no more starch (when reaction was over) and the order it went from fast to slow was pH11, 7, 5 and then 3. I wanted to know why pH 11would've been the quickest. (would it have something to do with another factor affecting the iodine colour change?)
