Investigating the effect of temperature on the position of the equilibrium among coulomb monoxide gas in excess sedimentary chloride ions Abdul Rahman Khalifeh Aim To carry off the counter intensify of the position of equilibrium between Co2+ (aq) of tautness of 0.3 jetty L-1 and Cl- of closeness 3.0 breakwater L-1 when placed at temperatures of 0°C, 95°C and 25°C. Hypothesis Since this reaction is endothermic, as temperature increases the equilibrium will play to the right according to Le Chateliers principle. Water would relocation the equilibrium to the left and the HCl would move the equilibrium to the right according to Le Chateliers principle. Variables drug-addicted variable(s) | Independent Variable(s) | Controlled Variables | The position of the equilibrium which is monitored by the colour change of the solution| The temperatures of 0°C, 25°C and 95°C. at which the reaction takes place| Same constriction of aqueous chloride ions (3.0 mo l L-1)| | | 6 test tubes of the same size, shape and volume.| | | Same concentration of aqueous cobalt ions (0.
3 mol L-1)| | | The same digital correspondence to 4 signifi crowd outt figures after the decimal h wholeow in order to have the same uncertainty for entirely measurements taken | | | The same of solution in all cases| tool starter| Chemicals| Equipment| (3) evidence tube| 600 g of Ice| gawp| (3)50 cm3 Beaker| 30.0000 g of CoCl2.6H2O| Test tube holder| Graduated cylinder- coke cm3| Concentrated HCl | digital balance to 4 significant figures| conic Flask 100cm3| | bunsen burne r burner| | | Thermometer| Method for t! he Control of Variables In order to obtain the consummate control of variables we must control all other factors poignant the position of the equilibrium. Hence the concentration of aqueous chloride ions and aqueous cobalt ions must be fixed and this can be make by measuring the mass of CoCl2.6H2O accurately by utilize a digital balance to 4 significant figures. In order to control the...If you want to fit a fully essay, order it on our website:
