Question

How will mistakenly using solution 1 to calibrate the spectrophotometer, instead of the blank affect the calcualted concentration of FESCN2+ at equilibrium and the calculated concentrations of Fe3+ and SCN- uncomplexed at equilibrium? 

The blank contained 5.00mL of 0.00200 M Fe(NO3)3 (in 0.1M HNO3) and 5.00mL of 0.1 M HNO3.

Solution 1 contained 5.00mL of Fe(NO3)3 (in 0.1M HNO3), 1.00mL of 0.00200 M NaSCN (in 0.1 M HNO3) and 4.00mL 0.1M HNO3. 

Fe3+(aq)+SCN-(aq)->FeSCN2+(aq)
