Why can you make the assumption that all of the SCN^- ions in solutions S2-S6 have been converted to FeNCS^2+ ions? Verify the assumption described in question 2. To do so, use your mean K_eq to calculate equilibrium SCN^- ion concentration in solution S6. The initial Fe^3+ ion concentration should be 0.0400 M; the initial SCN^- ion concentration is recorded on the first page of this report. You will have to use and ICE table and solve a quadratic equation.
