Question

Suppose the Kc value for Cobalt (II) hexahydrate is 6.80 and suppose upon heating the solution turned pink.  If a group of student started mixed 10.5 mL of a 1.25 M [Co(H2O)6]2+(aq) solution with 12.5 mL of a 1.55 M solution of NaCl(aq) with 15.25 mL of a 1.39 M [CoCl4]-2(aq) solution then what color is the solution at equilibrium?  

[Co(H2O)6]2+(aq)  +  4 Cl-(aq)      [CoCl4]-2(aq)  +  6 H2O(L)
