Investigating the effect of Temperature on the reaction between Sodium Thiosuphate and hydrochloric acid :: GCSE Chemistry Coursework Investigation

Investigating the effect of Temperature on the reaction in the midst of Sodium Thiosuphate and hydrochloric superman PlanningI am investigating the unlike temperatures on the reaction betweenSodium Thiosuphate and Hydrochloric stifling.The factors I could investigate would be temperature, concentrationand substances. I have chosen to investigate Temperature.I expect that the higher the temperature the much than rapidly the crosswould obscure. This is because the higher the temperature the more much the particles collide and react, when the particles collide moreoften they would collide harder because they have more energy, makingthe collisions bigger and faster, the collision success rate ishigher.I allow for make my investigation a fair test by safekeeping the quantities ofthe Hydrochloric acid at room temperature and Sodium Thiosuphateheated as hi-fi as possible. Also make sure the turn back clock isstarted at the same point each time a measurement is taken.I exit carry o ut the investigation by1. Set up the Diagram2. project the test tubes of Sodium Thiosuphate into the beaker above the Bunsen burner3. Put a thermometer into it4. Remove the test tube once its reached the desired temperature and shoot contence into the empty beaker5. As you begin to pour the test tube of Hydrochloric battery-acid contence into the beaker start the stop clock6. When the cross on the paper becomes obscured stop the clock and record the result7. Rinse out the beaker where the reaction took seat8. Repeat with five different temperatures, using ice to cool low-spirited the Sodium Thiosuphate, and repeat it all twice.The equipment I entrust use is Hydrochloric acid Sodium Thiosuphate 2 x Measuring cylinders 2 x tribulation tubes stop clock 2 glass beakers 2 thermometers Bunsen burner water system tripod heat mat gauge paper with pencil crossI will make sure my results are accurate by referring to graphs, e.g.if nonpareil point is greatly out of alignment, it should be repeated.Also I will make sure that the meniscus of the hydrochloric acid andThiosuphate is flat and not to atomic number 53 side of the test tube or measuringcylinder.I will take five measurements with a 10 gap interval and I will repeatthis twice and take an average to make my results more accurate.Back ground Research - Trial ExperimentI conducted a trial experiment to find out the correct quantities ofsodium thiosulphate and hydrochloric acid for the main experiment. Wewere aiming for the cross to disappear in around one minute.We demonstrate the more hydrochloric acid the slower the X disappeared.
