Chemistry Laboratory Report: Factors affecting reaction rates

Title: Factors affecting reception computesProcedure A: Effect of ConcentrationAim: To investigate how the intentness of a reactant affects the rate of reply. opening: The more than concentrated the reactant, the fast-paced the rate of reaction. Materials: 2M hydrochloric acrimonious result, nuclear number 12 fit, distilled piss, 4 test-tubes, measuringcylinder. Procedure:1)10mL 2M hydrochloric point termination is poured into a test-tube using a measuring cylinder. 2)A 3cm aloofness of milligram wire is added to the superman, and the stopwatch is started simultaneously. The period it takes for the atomic number 12 to leave into solution is recorded. This time is recorded in the results table. 3)The test-tube is rinsed thoroughly and flavor 2 is perennial using 8mL bitter mixed with 2mL water. 4)This is repeated for each paneling-water mixture, as shown in duck 1. Results:Table 1Volume of HCl(ml)Volume of water (mL)Time taken (s)100418252736664120Calculations:Table 2Volume of HCl(ml)Volume of water (mL)Concentration (mol/L)1002821.6731.4641.2Discussions:The reaction between magnesium and hydrochloric acid:Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g)Increasing the concentration of the hydrochloric acid will growth its solubility. The high(prenominal) concentration of acid plaza there ar more reactants per molecule, making the reaction of the magnesium more effective.

Sources of fault in this experiment:?The dilution process of the hydrochloric acid is very crude. This means that the reaction rate will be affected, exclusively non by a lot. ?The size of the magnesium wire is not equal. This will excessively affect the consistency of the results, but again, not by a lot. ?The recording of the time may not be absolutely accurate. The experiment could be change by reducing the sources of break i.e. handling the equipment as accurately as possible. Conclusion: The higher the concentration of the reactant, the higher the rate of reaction. If you wishing to get a full essay, order it on our website: Orderessay
