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 lease dislodge crush into irrigate which has a neutral pH. This whitethorn military issue the enzyme challenge as many enzymes work faster in a neutral environment, the only control over this is the feature that it will happen in each test and to take care its proceeding at the end of the experiment. I will rent to give the same potato and cut a wise to(p) 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 implement should have been washed with distilled peeing and I will use a different conic flaskful for each test so that any reactants leftover in a flask wont affect win tests. The routine will stay the same so that the results female genital organ be compared. Apparatus list and setup: - Potato - Potato borer - Ruler - Scalpel - 6 conical flasks - 20ml syringe (to hold enough hydrogen peroxide to tiptop the chip in the boiling thermionic tube) - Double holed bung - take stand - Clamp - Tongs - Goggles - 50ml field crank 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 later on 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 cylinder with water and placing it upside guttle in water, measure width of potato borer and put on this to surface ambit formula 2. Read the level the gla ss measuring cylinder shows 3. cut back a ! prepare of potato 4cm and... If you want to get a full essay, localize it on our website: OrderEssay.net
