Add 25 mL of [Co(H2O)6] 2 to an empty Erlenmeyer flask. Now add 12 M HCl in 1 mL increments until the equilibrium color has changed. ( Hint: Type in 1 for the volume to be transferred, and then keep clicking pour until you see a change, counting clicks to determine total volume added.) 2. Predict the effect of removing chloride ions. Now remove some of the free chloride ions by adding some silver nitrate (Hint: add 1 mL amounts of the silver nitrate successively until the equilibrium has been shifted instead of a whole bunch at once).
