You wish to measure the iron content of the well water on the new property you are about to buy. You prepare a reference standard Felt solution with a concentration of 5.23 x 10 * M. You treat 10.0 mL of this reference with HNO, and excess KSCN to form a red complex and dilute the reference to 50.0 mL. The diluted reference is placed in a cell with a 1.00-cm light path. You then take...
