An investigation to see how concentration affects The rate of reaction. Prediction: The higher the concentration of water mixed with the Hydrogen Chloride and Sodium Thiosulpate the slower the rate of reaction will be. Introduction: By adding the water into the experiment we are diluting the solution of the Hydrogen Chloride and Sodium Thiosulpate and therefore the water is slowing down the reaction time. The time taken for a reaction to take place is known as the rate of reaction and there are many things that can change the rate of reaction. They are: - The concentration of Sodium Thiosulpate and water. - The surface area of Sodium Thiosulpate and water. - What is done to the conical flask during the experiment (shaking). - Fair testing. - The temperature at which the reaction takes place, - Using a catalyst. Changing the concentration, will change the rate of reaction, this is because the higher the concentration the more particles of Sodium...
