Concentration of Fe(SCN)2+ in calibration Solutions-Recall that the concentration of Fe(SCN)2+ in the calibration solutions is essentially the concentration of SCN- initially in the solution. So, determine the concentration of SCN- initially in each of the 10.0 mL calibration solutions. This is a simple dilution. The data table from the experiment includes: Calibration Solution Blank #1 #2 #3 #4 0.2M Fe(NO3)3 in 0.5M HNO3 5.00mL 5.00mL 5.00mL 5.00mL 5.00mL 0.002M KSCN in 0.5M HNO3 0 0.50mL 1.00mL 1.50mL 2.00mL 0.5M HNO3 5.00mL 4.50mL 4.00mL 3.50mL 3.00mL So far I have: Fe(NO3)3 KSCN Fe^+3 +SCN^- --> Fe(SCN)^+2 I .2 .002 0 C -x -x +x E .2-.002 0 .002 MV=MV (.002M)(.5mL)=M(10mL) (.002M)(.5mL)=M 2x10^-4=M
