The volumes of a solution containing 1.10 ppm of Zn2+ shown in the table were pipetted into separatory funnels, each containing 5.00 mL of an unknown zinc solution. Each was extracted with three 5-mL aliquots of CCI4 containing an excess of 8-hydroxyquinoline. The extrats were then diluted to 24.0 mL and their fluorescence measured with a fluorometer. The results were the following.
