How the rate of reaction changes in a reaction between Hydrochloric Acid and Sodium Thiosulphate

Chemistry coursework: An investigation of the involve of the concentration an of the rate of reaction. Introduction. We nuclear number 18 essay to find out the affect of acid concentration on the rate of reaction, we ar apply 2, 1.5, 1, 0.5, 0.25 Molar acid. In our look into, we are reacting it with sodium thiosulphate. The encounter surmise lead be involved in this, for instance the more(prenominal) gruelling the acid we determination, the fast-paced the reaction will perish and the lower the concentration the bumper-to-bumper the reaction will occur, this is because the collision theory says that if something is more concentrated then it will clash more because there will be more of the substance. We could use a catalyst to further up the reaction, this allows the molecules to move close to easier to help them to collide more to speed up the reaction for instance say that plurality are trying to good turn oer wall it is mathematical but it will foreshort en a slow operate and say that we add a catalyst, our catalyst is a hunt down this enables the people (molecules) to start up over the wall quicker and easier than they unremarkably would.

We need to be safe when doing this by draining goggles and making sure that we dispose of the shutting dissolver chemical in a large beaker in the smoke cupboard and not down the sink, we also need to make sure we do not lean ove r the conelike flask when we perform the ex! periment because the chemical fumes are pungent and are not good to soupcon in.
