The questions below refer to the following system: Co(H2O)6 + 4 CI=C0C1 + 6H,O (pink) (blue) When cobalt(II) chloride is added to pure water, the Co-" ions hydrate. The hydrated form then reacts with the Cl ions to set up the equilibrium shown here. Which statement below describes the change that the system will undergo if water is added? Select one: O a. More chloride ions will be produced. O b. The equilibrium will shift to the right. O c. There will be less of the hydrated cobalt ion at the new equilibrium position. O d. More water will be produced. O e. The color will become more blue. here to search F4 F6 F7 F8 F10 F11 F12 Prisc %23 %24 & 4. 5 6 E R T G B
