Cool Blue Gatorade Concentration Lab Report

Claim: The concentration for Cool Blue Gatorade is 1.19E-06, and the Glacier Frost’s concentration is 2.78E-07.

Error: In our experiment, there was a source of error because in the Concentration vs. Absorbance graph’s line of best fit, there was a y-intercept, but there isn’t suppose to be one since the concentration is 0, the absorbance should be 0. There are no particles in the solution, distilled water, so nothing should be absorbed. This error could have been caused by the leaving the diluted solution out too long, so the water in the solution could have evaporated, leaving only the blue dye. It is not a diluted solution if there is just dye left in the beaker because it would go be a higher concentration than the actual solution’s concentration
