Robert Nelson 10 H Chemistry Coursework Plan Rates Of Reaction Outline of Method In my experiment, I will mix Sodium thiosulphate solution and Hydrochloric acid. I will time how long it takes for the cross to disappear with different concentrations of sodium thiosulphate solution. The solution goes cloudy because sulphur is produced in the reaction. Safety Hydrochloric acid is corrosive. I will wear safety goggles at all times to ensure my eyes are not damaged from the substances. I will also clean all spillages. Apparatus Conical Flask, 2x Measuring Cylinders (10 ml and 50 ml) 3x Beakers For Solutions Stop Watch Piece of Paper Pencil Thermometer Chemicals I will measure 50 ml of sodium thiosulphate solution using concentrations of 0.03,0.06,0.09,0.12 and 0.15(these are measured in molars).I will use a 50 ml measuring cylinder to measure this volume. I will measure 10 ml of Hydrochloric acid using a 10 ml measuring cylinder with concentration of 1 Molar. Equation Sodium thiosulphate + Hydrochloric acid ----> Sodium chloride + water + Sulphur +...
