Methylene Blue Lab Report

n this lab, everyone got a flask which we then drew a pumpkin face on. Then we mixed 42 mL sodium hydroxide solution, 10 g of glucose, 1 mL, 1 L of water and Methylene blue solution and leave it undisturbed. The blue solution turned clear and when we added the yellow food coloring it turned an orange color. The solution then turned dark blue once the solution was shaken vigorously. This reaction occurred because the oxygen oxidized the methylene blue.In the oxidized state the methylene blue shows a deep blue color this corresponds with what happened first in our lab when the materials where mixed. In the reduced state methylene blue turned to a clear color, which is the same result as what happened to our solution in the flask when we left
