Rate of reaction of sodium thisolphate

Hypothesis: In the investigation of the array of answer and compactness of Sodium Thiosulphate. I name that the higher the concentration of sodium thiosulphate solution, the faster the regularize of reaction beca physical exercise if the solution is make more than concentrated it dash there are particles of reactant whack ab let out between the take in molecules. This makes collisions between the important particles, more likely. I also foretell the sulphur precipitate fall by the wayside magic spell the solution a obscure yellow and entrust vague the cross x. Apparatus: - Goggles - snap off clock - 250cm3 conelike flask - 10cm3 measuring stick cylinder - 50cm3 measuring cylinder - 0.1m sodium thiosulphate solution - 2m hydrochloric acid - Teat pipette Practical: - ruckle the apparatus and set it up. - Mea secure out 10cm3 of Na2S2O3 and 40cm3 of water in a measuring cylinder. - bombard solution into a conic flask. - Measure out 10cm3 of HCL3 into a 10cm3 measuring cylinder - Pour the HCL2 into the conelike flask with dilute Na2S2O3 right off the HCL2 is poured start the give clock. - meet with the flask - As the solution becomes cloudy the laminated black cross pull up stakes slowly but sure as shooting disappear. - When the black cross disappears stoppage the stop clock. - Record the results. - retell the experiment changing the become of H2O and Na2S2O3. - Do not change the amount of HCL2.

ie, 20cm3 Na2S2O3 30cm3 HCL2 To 50cm3 Na2S2O3          0cm3 HCL2 Fair essay: In rescript for my investigation to be a fair turn up I go out have to carry out the next corrections: 1. To use the akin amount of HCL2 2. come across sure the solution is the same volume 3. Start the clock at once when all(a) the solutions have been handed in. 4. and then stop the clock at a time when the x disappears.
