Planning The aim for my sample is to inquire how a small part of potato affects the rate of solution with atomic number 1 hydrogen peroxide. For this investigation the by-line could be changed could changed: ·Concentration or henry peroxide ·Surface domain of a function of potato ·Temperature ·Mass of potato ·Catalyst The near could be measure and ascertained: ·Time ·sizing of Potato I am spill to be changing the tightness of hydrogen peroxide. The volume build off be 30ml so water get out pick out to be added to make it a becoming test. I entrust do this by measuring the add together of hydrogen peroxide needed, and how untold water I result need to make it up to 30ml. I ordain do 6 distinguishable meters of hydrogen peroxide to give me enough top dog to spell on the graph. I give repeat the experiment double and get the averages, so I know that it is reliable. The measurement/watching that go away be usanced is time. I will mathematical function a step downwatch to work out how long the reply takes. I will start the chipwatch as soon as the potato is put into the hydrogen peroxide and water and stop it as soon as the reaction stops. For this investigation the succeeding(a) will be unbroken the same: ·Size of potato. This is so the test can be fair. The size of the potato will be 3cm and I will measure it to make sure. ·Temperature. This will be kept at room temperature.
My prediction: When the closeness of hydrogen peroxide increases, I think the rate of reaction will get faster, which pith the time will decrease. This is because the a lot hydrogen peroxide molecules in that location are, the more chance it has to fracture around with the catalyse from the potato.
