1. Consider the following reaction: Fe³+ + SCN- FeSCN²+ the Fe³+ and SCN ions are essentially colourless and the FeSCN2+ species is blood red in colour. What physical changes in the above equilibrium solution would you expect to see if: (a) SCN were added to the above equilibrium solution? (b) OH were added to the above equilibrium solution? (HINT: Look up the solubility of Fe(OH)3) (c) Agt were added to the above equilibrium solution? (HINT: Look up the solubility of AgSCN)

1. Consider the following reaction:
Fe³+ + SCN = FeSCN²+
the Fe³+ and SCN ions are essentially colourless and the FeSCN²+ species is blood red in
colour. What physical changes in the above equilibrium solution would you expect to see if:
(a) SCN were added to the above equilibrium solution?
(b) OH were added to the above equilibrium solution?
(HINT: Look up the solubility of Fe(OH)3)
(c) Agt were added to the above equilibrium solution?
(HINT: Look up the solubility of AgSCN)
