Ok, as far as i know, the optimum pH of catalase is 7.5, right? So why am i getting a really fast rate for pH 11? Look at my average results:

pH Average time (mins)
3 20.32
5 7.84
7 6.62
9 7.11
11 6.9

Please someone explain to me why the rate at pH 11 is so high- is the buffer reacting with the hydrogen peroxide or something?
