An investigation of the affect of the concentration an of the rate of :: GCSE Chemistry Coursework Investigation

An investigation of the affect of the concentration an of the rate ofreaction.Introduction.We be move to find out the affect of acrimonious concentration on the rateof reaction, we are using 2, 1.5, 1, 0.5, 0.25 Molar acid. In ourexperiment, we are reacting it with atomic number 11 thiosulphate. The collision surmise will be involved in this, for character the more concentratedthe acid we hold, the faster the reaction will fall out and the lower theconcentration the slower the reaction will occur, this is because thecollision theory says that if something is more concentrated then itwill collide more because on that point will be more of the substance. Wecould use a particle accelerator to hurrying up the reaction, this allows themolecules to move around easier to help them to collide more to hieup the reaction for instance say that people are trying to get overwall it is possible but it will tamp bulge out a slow process and say that weadd a catalyst, our catalyst is a ladder this enables the people(molecules) to get over the wall fast and easier than they normallywould. In this experiment we need to control the marrow of acid,amount of peeing, chemicalswater temperature amount of sodiumthiosulphate and to all agree when the x is bypast on the paper. We needto be safe when doing this by wearing gawp and making sure that wedispose of the end result chemical in a large beaker in the fumecupboard and not down the sink, we also need to make sure we do not tip off over the conical flaskful when we perform the experiment because thechemical exhaust fumes are pungent and are not good to breath in.Method.We are going to measure the rate of reaction by how fast or slowly themix of chemicals and water goes unfixed by placing a part of paperwith a cross on it underneath the conical flask and all agreeing whenit has disappeared from sight.In this experiment we will need to use the pursualEquipment UseStop clockTo time the experimentConical flaskTo collect all the chemicals together inBuretteTo measure accurately all the chemical and waterSodium thiosulphateChemical used in this experimentHydrochloric acidChemical used in this experiment, we will use 2, 1.5, 1, 0.5 and 0.25molar strengthsWaterUsed in this experiment, used in dilutions musical themeUsed along with cross of colour to determine when mixture is cloudyenoughBeakersUsed to hold the chemicals and waterDilutionsTo obtain the different strengths of hydrochloric acid we will need todilute 2 molar acids and dilute it with water to reach the appropriate
