The Effect Of Concentration And Temperature On Reaction Rate Planning- Aim- To see how the temperature of both substances and concentration of Sodium Thiosulphate affects the rate of the reaction; Sodium Thiosulphate + Hydrochloric Acid › Sodium Chloride + Water + Sulphur Dioxide + Sulphur Na2S2O3 2HCl 2NaCl H2O SO2 S Apparatus- Beaker Water Sodium Thiosulphate Hydrochloric Acid 2 x Measuring Cylinder of a 1cm3 scale Conical Flask of a 5cm3 scale White Tile marked with a black cross Stop Watch Tripod Gauze 2 x Boiling Tube Thermometer Goggles Apron Preliminary Method- Concentration- For the concentration section of the experiment a fairly simple method is all that is required. 10cm3 of Sodium Thiosulphate, of a concentration of 10,15,20,25,30,35,40 and 45d/m3 is measured, using one of the aforementioned measuring cylinders, and then poured into the conical flask, which is sitting upon the white tile. 15cm3 of Hydrochloric Acid is then measured with the other cylinder and poured into the conical flask containing the Sodium Thiosulphate. The stopwatch is started. Timing continues until...
