Investigating the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid

Investigating the rate of reaction between sodium Thiosulphate and Hydrochloric acidulated Diagram Aim : We did 4 experiments to give away show up how the rate of reaction changes with differing ingresss of sodium Thiosulphate, Hydrochloric venereal disease and pissing. As an in incompatible and stable liquid, urine was utilise to alter concentration of Sodium Thiosulphate without changing the end heart of dissolving agent. All the atoms in a water system molecule induce a honorable outer shell, so they would not react with the other chemicals. Equipment : Beakers, meter cylinders Clamp support and Clamps Black paper tube a abstemious probe and Blue box Datalogger Lamp Total of 30cm3 H 0, 50cm3 Na S O , 12cm3 HCl Method : We motiveed to change the concentration of Sodium Thiosulphate and Hydrochloric Acid, just without changing the overall quantities. To do this, the Sodium Thiosulphate and water were interracial at different ratios, with always a uniform amount of acid. The table down the stairs shows the 4 different experiments, and what each solution composed of. The Graph column relates to the graphs taken from the Datalogger for that experiment, which be included at the back of this piece.

Sodium Thio-sulphate (cm3)         Water (cm3)         Hydrochloric Acid (cm3)         Graph number 20         0         3         DPPAS_02 15         5         3         DPPAS_03 10         10         3         DPPAS_04 5          15         3 !         DPPAS_05 We did not do the experiment in which 0cm3 Sodium Thiosulphate and 20cm3 water were used, as in that respect would have been no reaction. In sum up, there were always 20cm3 of water and Sodium Thiosulphate, with 3cm3 Hydrochloric Acid, giving a total solution of 23cm3 The sable tube was put around and below the beaker to help anticipate any unwanted light from entry the light probe, as this would have impaired our results. The reason we used a Datalogger and light probe instead of the old cross... If you want to get a full essay, order it on our website: BestEssayCheap.com
