Question

You decide to make a calibration curve, to determine the relationship between concentration and the absorbance measurements. You believe, based on your knowledge of the plant’s equipment that the concentration of the unknown dye should be between 0.35M and 0.5M. The solutions available to you are shown in the table below.
Identify by clicking a box below which set of solutions would be the most appropriate (the best) to use for a calibration curve to solve this problem.
A 1,8 B 4,5,6,7 C 2,3,4,5 D 3,4,5,6 E unknown, 2,4,6 Solution Unlabeled Bottlel? Standard 1 Standard2 Standard 3 Standard 4 Standard 5 Standard 6 Standard 7 Standard 8 Concentration 0.1M 0.2M 0.3M 0.4M 0.5M 0.6M 0.7M 0.8M

Explanation / Answer

D)3,4,5,6

These solutions are in the range 0.3-0.6 M that corresponds to our estimated concentration of unknown.

We can easily determine the unknown concentration from the calibration curve of this range.
