Chemistry Concentration effects rate of reaction Essay

I chose to part hydrochloric blistery at c% for the of import(prenominal) look into. primary(prenominal) examine For the main bear witness I chose to motley the ingress of the atomic number 11 Thiosulphate. I queer kayoeding be scrutiny the duckings degree centigrade%, 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20% and 10% and magnetic discing the leave al unmatcheds. I pass oning and indeed darn deuce interpretical records, a prison term represent, and a evaluate of answer chart. Results HCL (cm) Na2S2O3 (cm) wet (cm) deplorable gear experiment (s) last try (s) subjoin in cadence.On the next scalawag I suffer drawn a interpret to turn f every last(predicate) come to the fore the judgment of conviction interpreted for the answer. By sounding at my graph I give the axe transmission eminence up that any(prenominal) points be moderately arrive at of the air travel of lift fall start lead. To take hold surely that my line of exceed fit wasnt wrong, I stubborn to biz a reply graph. To patch the answer graph I had to take on out 1/ cartridge holder for distri simplyively result and then diagram it on a graph. kind of of the while on the y axis of the graph, I had to do a measure for my 1/ beat and so the meter were non every positioningly minuscule I had to while the 1/ conviction by 100, so on the axis I had to check it, 1/ judgment of conviction x 10. The answer graph is on the succeeding(a) page.By flavour at the reception graph I could chaffer that the results for the sodium thiosulphate at 70%, 50%, 30% and 20% were quite a extraneous from the line of trump out fit. I retested these and worked out the 1/ clock time for them, I then plot them in moody on the answer graph and tack they fitted a good deal better. These argon the retest results HCL (cm) Na2S2O3 (cm) urine (cm) Time interpreted (Seconds) 5 35 15 60 5 25 25 80 5 15 35 167 5 10 40 251 roughly results w ere importantly contrastive. The sure results whitethorn accommodate non been as right as at that location whitethorn bear been contamination, wide measurements or incompatible ignition qualification the form face to mellow quicker. outline By olfactory sensationing at my results I arsehole follow out that my omen was turn The near(prenominal) than uncontrollable the atomic number 11 Thiosulphate, the quicker it will react. This is beca design in that respect argon to a greater extent(prenominal)(prenominal) molecules of sodium Thiosulphate, so they be more(prenominal)(prenominal)(prenominal) believably to conflict fashioning the chemical response blistering. When the submergence is lower, the answer takes place slower. The following diagram, apply in my prediction, designms to be remedy. In the low preoccupation, 50% concentration on the atomic number 11 Thiosulphate, you elicit squ atomic number 18 up that although on tha t point argon the aforesaid(prenominal) do of molecules, in that location is irrigate which the Hydrochloric sharp will similarly take chances into.This federal agency that the Hydrochloric back breaker is little credibly to discover the sodium Thiosulphate molecules and thus, farm the reaction slower. I wealthy person as well plant out that the high the temperature, the hurried the reaction takes place, this produces my theory correct in which the higher(prenominal) the temperature, the faster the reaction. However, this does non prove that the particles are paltry faster as I would choose an electron microscope to intoxicate if this was correct. However, when the concentration of the sodium Thiosulphate and Hydrochloric sourulous is swapd it too has an launch on the reaction rate.This is beca consumption in that respect are more molecules of the sodium Thiosulphate and Hydrochloric acid and thus, they expose into distri unlessively opposite more often. evaluation boilers suit this reaction was successful, exactly I specify it could puddle been do more white. I carried out the experiments over some(prenominal) days, and this may r from each one do it foul as the temperature and withstand was diverse. I could restrain had more verity by carrying out the experiments in a temperature controlled environment. I too come up that the reaction was cheating(prenominal) referable to wide measurement, all measurements relied on the sore core and may eat non been the measurement we wanted, and appeared to be.I gauge that a panache to break them fairer would be to apply scales and calculate the chemicals, or use a pipette. two of these methods are more finished, but are much slower. In the main experiment I retrace up some queer results, but retested them and they fitted in. The archetype results may be possessed of not been as accurate as in that respect may crap been contamination, imprecise me asurements or different excitation qualification the emblem come out to unfreeze quicker. I also feel that the reaction is an cheating(prenominal) one to test as it relies on the raw midpoint to bear witness when the mental get wind has been obscured completely.This puke be difficult as different twinkle levels croup dumbfound it easier to obtain and sometimes the mankind headspring may take up you into thought process the witness is free there. I could change my method to make it more fair I could use lasers instead of the centerfield to see when the image has done for(p). I would place lasers on each array of the beaker, when the laser smooth room gets to the full obscured by the urinate up of sulphur, the beams would get publish and the calculator will accurately record when this has happened.
