pH

[meee]

hi.

can anyone help me with some background info to help me with my experiment in biology.
i need to know the optimum pH for potato and apple when decomposing H2O2, however i cannot find any thing on the internet which is of any use to me.
if anyone knows please help as i am really stuck. i'm not sure if that because apple is slightly more acidic that it has a different optimum ph if so what is it plz. n also in my hypothesis do i need 2 put what i think will happen exactly ie. the pH lebels. thanks meee .

Are you testing apples/potatoes or enzymes?
