Question:
You have been given a jar of red fruit punch and been asked to determine the concentration of red dye in the fruit punch. You obtain a stock solution of this red dye and it has a concentration of 0.00113 M (in the lab room, the stock solution is found in the hood). You take 10.0 mL of this stock solution and dilute it to 100.0 mL. You call this your standard solution. Using a colorimeter, you determine that the red dye standard absorbs green light (the complementary color) with an absorbance value of 0.65.
