Title: Factors affecting reaction ratesProcedure A: Effect of ConcentrationAim: To investigate how the concentration of a reactant affects the rate of reaction. Hypothesis: The more concentrated the reactant‚ the faster the rate of reaction. Materials: 2M hydrochloric acid solution‚ magnesium wire‚ distilled water‚ 4 test-tubes‚ measuringcylinder. Procedure:1)10mL 2M hydrochloric acid solution is poured into a test-tube using a measuring cylinder. 2)A 3cm length of magnesium wire is added to

No; the experiment was not successful‚ because it did not show the correct fluorescence gradation of the serial dilution of the DNA concentration. As shown by the picture‚ only the first drop of the DNA/EtBr mixture for the DNA standards fluoresce brightly under the UV light‚ while the other spots for both the DNA standards and the unknown DNA standards were all dimly fluoresce. This was due to pipetting error; the tip of the pipette did not touch the liquid (TE) in the micro-centrifuge‚ so no DNA

An experiment to investigate the effect of temperature on the rate of reaction of the Enzyme Trypsin. Aim: This investigation was on the effect temperature has on the rate that the enzyme trypsin hydrolyses its substrate‚ a protein found in milk (casein). This investigation was conducted under controlled conditions‚ the temperature being the changeable variable. Trypsin and its substrate (powdered milk which is a source of the protein casein) were heated in a water bath. The contents of the two
