To investigate the effect of surface area on the rate of reaction using the enzyme Catalase, found in potato, and the substrate Hydrogen Peroxide.

Hydrogen bleach has an acidic pH which render educate crush into piddle system which has a neutral pH. This whitethorn publication the enzyme challenge as many enzymes work faster in a neutral environment, the only control over this is the event that it will happen in each test and to aim its proceeding at the end of the experiment. I will command to give the same potato and cut a impudently curb at each stage of the experiment as the catalase may become effected by exposure to the air. This may effect results so I will keep the hitchs as equivalent as possible. The utensil should have been washed with distilled water and I will use a different conelike flaskful for each test so that any reactants left(p) in a flask wont affect progress tests. The routine will stay the same so that the results feminine genital organ be compared. Apparatus list and setup: - Potato - Potato borer - Ruler - Scalpel - 6 cone-shaped flasks - 20ml syringe (to hold enough h ydrogen peroxide to parcel out the chip in the boiling render) - Double holed bung - income tax return stand - Clamp - Tongs - Goggles - 50ml field ice rink nib cylinder (to measure gas produced accurately and allow situation for the displaced gas.

As the cylinder is larger than necessary I can take the next reading directly after the original without having to fill the cylinder as much) - Bowl of water - Hydrogen peroxide 20vol - Splint - Timer - Delivery tube - Tile diagram Method 1. Set up apparatus including filling ice-skating rink cylinder with water and placing it upside rarify in water, measure width of potat o borer and restrain this to surface ambit! formula 2. Read the level the glass measuring cylinder shows 3. cut back a nibble of potato 4cm and... If you want to get a full essay, launch it on our website: BestEssayCheap.com
