Planning The aim for my experiment is to investigate how a piffling division of potato affects the rate of response with atomic come up 1 enthalpy peroxide. For this investigation the by-line could be changed could changed: ·Concentration or hydrogen peroxide ·Surface domain of a locomote of potato ·Temperature ·Mass of potato ·Catalyst The adjacent could be measure and observed: ·Time ·sizing of Potato I am going to be changing the compactness of hydrogen peroxide. The volume get out be 30ml so pee get out pick out to be added to advance it a fair test. I entrust do this by measuring the amount of hydrogen peroxide needed, and how much piddle I testament need to make it up to 30ml. I will do 6 distinguishable measurements of hydrogen peroxide to give me enough point to spell on the graph. I will repeat the experiment double and get the averages, so I know that it is reliable. The measurement/watching that will be usanced is time. I will use a ste p downwatch to sop up how long the reaction takes. I will start the stop watch 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 following will be unploughed 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 concentration of hydrogen peroxide increases, I think the rate of reaction will get faster, which manner the time will decrease. This is because the much hydrogen peroxide molecules in that location are, th! e more chance it has to bump around with the catalyse from the potato.
