Investigating the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid

Investigating the rate of reaction between atomic number 11 Thiosulphate and Hydrochloric tart Diagram Aim : We did 4 experiments to give away taboo how the rate of reaction changes with differing ingresss of sodium Thiosulphate, Hydrochloric point and pissing. As an unmoving and stable liquid, piddle was utilise to alter concentration of Sodium Thiosulphate without changing the end heart of dissolving agent. All the atoms in a irrigate molecule befuddle a expert outer shell, so they would not react with the other chemicals. Equipment : Beakers, touchstone cylinders Clamp support and Clamps Black paper tube ethereal 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 unalike ratios, with always a unceasing amount of acid. The tabl e 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 atomic number 18 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     Â Â Â Â Â 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 glowering tube was put around and below the beaker to help counteract any unwanted jobless 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
