Homework Help: CHEMISTRY HELP! ICE TABLES?

Posted by Taylor on Thursday, January 15, 2009 at 7:04pm.

At a certain temperature, K = 9.1 10-4 for the following reaction.
FeSCN2+(aq)= Fe3+(aq) + SCN -(aq)

Calculate the concentrations of Fe3+, SCN -, and FeSCN2+ in a solution that is initially 4.0 M FeSCN2+.



OKAY SO i started by doing an ice table

with FeSCN2+(aq)= Fe3+(aq) + SCN -(aq)
I 4 M 0 0
C -x x x
E 4-x x x

and then solving for K
K=prod/react

and then quadtratic formula

how is this wrong?
