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 between Sodium Thiosuphate and hydrochloric acid PlanningI am investigating the different temperatures on the reaction betweenSodium Thiosuphate and Hydrochloric acid.The factors I could ask would be temperature, c erstntrationand substances. I have chosen to investigate Temperature.I predict that the high the temperature the more rapidly the crosswould obscure. This is because the higher the temperature the moreoften the particles conflict and react, when the particles collide moreoften they would collide harder because they have more energy, makingthe collisions bigger and faster, the collision success locate ishigher.I testament make my investigation a fair raise by keeping the quantities ofthe Hydrochloric acid at room temperature and Sodium Thiosuphate change as complete as possible. as well make sure the plosive consonant clock isstarted at the same point each time a measurement is taken.I will carry pop out the investigation by1. Set up the Diagram2. Put the sieve tubes of Sodium Thiosuphate into the beaker supra the Bunsen burner3. Put a thermometer into it4. Remove the test tube once its reached the desired temperature and pour contence into the empty beaker5. As you begin to pour the test tube of Hydrochloric 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 place8. Repeat with five different temperatures, using meth to cool down the Sodium Thiosuphate, and repeat it all twice.The equipment I will use is Hydrochloric acid Sodium Thiosuphate 2 x Measuring cylinders 2 x Test tubes stop clock 2 glass beakers 2 thermometers Bunsen burner water tripod heat mat gauge paper with pencil crossI will make sure my results are accurate by referring to graphs, e.g.if one point is greatly out of alignment, it should be repeated.Also I will make sure that the meniscus of the hydrochloric acid andThiosuphate is forthwith and not to one side of the test tube or barcylinder.I will take five measurements with a 10 violate interval and I will repeatthis twice and take an average out to make my results more accurate.Back ground Research - Trial proveI conducted a trial experiment to find out the remunerate quantities ofsodium thiosulphate and hydrochloric acid for the main experiment. Wewere aiming for the cross to disappear in almost one minute.We found the more hydrochloric acid the slower the X disappeared.
