Question

The complex ion Co(H2O)6(2+)(aq) is pink when placed in solution. Addition of chlorine ions creates an equilib?

The complex ion Co(H2O)6(2+)(aq) is pink when placed in solution. Addition of chlorine ions creates an equilib?

The complex ion Co(H2O)6(2+)(aq) is pink when placed in solution. Addition of chlorine ions creates an equilibrium with CoCl6(4-) in the solution, which is blue in color.

a. write the balanced reaction for the equilibrium. if CoCl6(4-) solubility is endothermix, predict what will happen to the solution color of the solution is heated.

b. what will happen if the soution is cooled?

PLEASE HELP!!!!!

Explanation / Answer

a) Co(H2O)6 2+(aq) + 6Cl- CoCl6(4-) + 6H2O when sol is heated sol colur becomes more blue in colour since high temp favours endothermic process b) if sol is cooled sol becomes more pink in colour
