For each event stated, indicate how the concentration of each species in the chemical equation will change to re-establish equilibrium. An up arrow indicates an increase in concentration, a down arrow indicates a decrease in concentration, and leaving it blank means there is no change in the concentration.

CoCl2−4(aq) + 6H2O(l) ↽⇀ 4Cl−(aq) + Co(H2O)2+6(aq)
a. increasing the concentration of Cl−
b. decreasing the amount of H2O
c. increasing the concentration of CoCl2−
