You are assigned to measure the amount of salicylic acid in a wart removersolution. Salicylate ion reacts with an Fe³+ ion to form a complex ion thatstrongly absorbs light at 528 nm. You prepare standard solutions of knownsalicylate concentration. You add 5.00 mL of 0.025 M FeCl3 to each standardsolution and dilute each solution to a total of 10.00 mL. The concentration ofsalicylate in each solution is given in the table below. You then measure theabsorbance of each standard solution. The data are shown below.What is the concentration of salicylate in mg/dL in an unknown salicylatesolution whose absorbance is 0.185?
