Rates of Reaction
Experiment 1 Investigating the Effect of Temperature on Reaction Rate Level 1 SciPad page 126 Aim : I want to investigate how temperature effects the rate of reaction. Equipment: A beaker, conical flask Measuring cylinder Stopwatch Black cross on paper Water bath, Thermometer 0.1mol/L sodium thiosulfate 2.0mol/L hydrochloric acid Method: Put the 'X' on the bench mat and put the conical flask on the paper. Measure 50mL of sodium thiosulfate solution and put it in the beaker. Record the temperature of the sodium thiosulfate Measure 5mL of HCl and pour this into the conical flask. Pour the sodium thiosulfate into the conical flask, start the stopwatch and swirl the flask. Time how long it takes for the cross to disappear when viewed from above Wash out the flask thoroughly. Repeat the experiment, using a water bath to heat the sodium thiosulfate solution to 30degrees, 40degrees and 50degrees. Keep the volume of the acid the sa...
