The effect of concentration on the rate of reaction-chemistry- Steven Everill 11g Preliminary work For the preliminary work I heated the Hydrochloric acid and the Sodium thiosulphate to 50 degrees Celsius then mixed them and times how long the reaction took and then did the same experiment at room temperature and then cool the two chemicals to 8 degrees Celsius and time the reaction, I recorded the results and found my results would be accurate if I continued the experiment at room temperature. Pre-lim results Room temp = 29.37 Ice = 26.40 (8 d/c) Heat = 01.72 (50 d/c) Equipment Sodium thiosulphate (Na2 S2 O3) of different concentrations Hydrochloric acid (HCl) Tile marked with a cross Measuring cylinder (x2) Beaker (x2) Test tube (x2) Stopwatch conical flask Aim I want to find out what effect concentration has on the rate of reaction by changing the concentrations of na2s2o3 and mixing it with HCl and timing it until I cannot see the cross placed underneath the beaker...
