State keq to calculate the scn- concentration

Reference no: EM13181079

Use the mean value that you determined for Keq to calculate the SCN- concentration in a solution Fe3+ concentration was 4.00 X10-2M and initial SCN- concentration was 1.00 X10-3 M. Is all of theSCN- in the form ofFeNCS2+?

Kc=[FeNCS^2+]/[Fe^3+][SCN^-]

AVG Keq= 292

I made the ice chart and determined
Keq=292=(x)/(0.04-x)(0.001-x)
