How Concentration Affects Rate of Reaction Aim: to find how Concentration affects the rate of a chemical reaction. Diagram: Equipment: * Clamp Stand * Burette * Hydrochloric acid * Sodium Thiosulphate * Stop watch * Conical Flask * Measuring Cylinder * Clamp Stand * Clamp * Safety goggles Method: 1. Set up apparatus as shown in diagram. 2. Mark a thick black cross onto the white tile 3. Pour 25cm³ of Sodium Thiosulphate into a measuring cylinder and pour into Conical flask 4. Pour Hydrochloric acid into a Burette 5. Place Conical flask with Sodium Thiosulphate onto the tile 6. Open tape on Burette allow 25cm³ of hydrochloric acid to flow in to the conical flask 7. Then start stop watch straight away 8. Looking straight through the mixture wait to you cant see cross and stop the stop watch. Prediction: I think that the higher concentration used for the experiment the quicker the reaction will finish. I think this as if there was higher concentration of sodium thiosulphate then there is...
