n Experiment 14, a Clock Reaction was set up by combining the following reagents in a 250 mL flask. KI(aq) [0.2 M], 10.0 mL Starch [1%], 0.6 mL Na2S2O3(aq) [0.40 M], 0.40 mL KNO3(aq) [0.20 M], 19.0 mL EDTA(aq) [0.10 M], 1 drop The reaction began when 10.0 mL of (NH4)2S2O8 (aq) [0.20 M], ammonium peroxydisulfate, was added to the flask and it took 262 s for the solution to turn dark blue. If the student set up the same reaction in a new flask, but used 0.8 mL of Na2S2O3(aq), approximately how long would it take for the solution to turn blue
