In this section you should record any visual observations you make for denisty (colors,appearances of water, physical states, etc).You should also record any numeric observations (masses, volumes, concentrations).Make sure they are clearly organized and labeled so it is clear what the observation of Kinetics – The Iodine Clock Reaction: The reaction is initiated by mixing solutions A1 and B and gently swirling until thesolution turns blue. Record the time in seconds for the solution to turn blue or purple Solutions for flasks A and B: Flask Label is A3, Volume of Starch which is 1.00, Volume of Na2S2O3 (mL) which is 2.00, Volume of 0.200 M KI (mL) which is 4.00, and Volume of 0.200 M KNO3 (mL) which is 4.00. Results: Trial 1: was 76 seconds to turn from clear to purple, trail 2: was 88 seconds to turn purple, trail 3: which was 102 seconds to turn purple, trail 4: was 82 seconds to turn purple again, and lastly trail 5: which was 93 seconds to turned from clear to purple.
