A tetraaquasalicylatoiron (III) complex calibration solution is prepared by transferring 0.50mL of a 0.00900 M salicylate dianion stock solution into a 10.00mL volumetric flask as well as diluting to the 10mL mark with 0.02 M iron(III) chloride that has been buffered to a pH of 1.6. Explain what is the molarity of the complex in the flask after dilution and would love the steps to get to this.
