Find the concentration of Fe(SCN)2+ for each test tube.

30mL of 0.200M Fe(NO3)3 was prepared. Then, 15mL of 0.0020M KSCN was prepraed in another beaker. 10.0mL of prepraed KSCN solution was pipetted into a 100mL flask and the volume was brought up to 100.0 mL with distilled water.

Then, five solutions were prepared according to the chart.
