Investigating the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid

Investigating the enumerate of respondion surrounded by atomic number 11 Thiosulphate and Hydrochloric erosive Diagram Aim : We did 4 experiments to stool away out how the rate of reaction changes with differing ingresss of Sodium Thiosulphate, Hydrochloric Acid and pissing. As an inert and permanent liquid, peeing was utilise to warp concentration of Sodium Thiosulphate without changing the end heart of dissolving agent. All the atoms in a body of water molecule put one over a proficient outer(prenominal) shell, so they would not react with the other chemicals. Equipment : Beakers, Measuring cylinders Clamp support and Clamps Black musical composition tube Light 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 boilers suit quantities. To do this, the Sodium Thiosulphate and water were interracial at varied ratios, with always a unremitting amount of acid. The table worst the stairs shows the 4 disparate experiments, and what each solution be of. The graph column relates to the graphs taken from the Datalogger for that experiment, which are included at the back end of this piece.

In marriage up, there were always 20cm3 of water and Sodium Thiosulphate, with 3cm3 Hydrochloric Acid, giving a total solution of 23cm3 The swarthy tube was put somewhat and below the beaker to help keep any unwanted visible radiation from entry the deject probe, as this would have impaired our results. The apprehension we used a Datalogger and light probe instead of the previous(a) cross... If you want to get a full essay, order it on our website: Orderessay
