...dye is evenly distributed throughout the mixture unlike water and oil that doesn’t mix completely. 6. Duration Time to de blue 5's 1 min. 45 sec. 10's 1 min 59 sec. 15's 2 min 14 sec. Vitality Time Hard 2 min, 20 sec. Medium 1 min. 18 sec. Soft 58 sec. # Of Shakes Time 5 33 sec. 10 53 sec. 15 1 min. 52 sec. 7. The other reaction is oxygen. When the solution is shaken the solution is oxidized causing the blue color. 8. Does the reaction eventually run down? No. It can get the same deep blue and take the same amount to de-blue no matter how many times you do it. (Perform the experiment) 9. Could the reaction occur without air in the flask? Yes. Even deluded there was a small amount of air in the top that caused the solution, when shaken, to turn a light tint of blue. 10. If you were told that reactant A causes B to turn blue and C causes the blue color to disappear could you explain why the reaction runs down? Yes, if you know what is used to cause the blue color and what makes it disappear then you would definitely be able to explain why the reaction runs down. If caused the color to disappear then less of c would slow down the process of the clearing of the water. 11. The decadents of Martin Fugate and Elizabeth Smith have a strange condition where their skin is a blue color ranging from light blue to almost purple, hereditary methemoglobinemia. “It was caused by an absence of the enzyme diaphorase from their red blood cells.” Dr. Cawein, who treated them, discovered that injections of methylene blue would change their skin from the bluish color back to normal. “Cawein packed his black bag and rounded up Nurse Pendergra...
