4 Nov 2009, 11:50 PM | Re: ahhhh quick HELP!!! yep cobalt complex ions Co(H2O)6 +2 + 4Cl - --> CoCl4 -2 + 6H20 (sorry dont know how to do indices) it turns pink on the left hand side and blue on the right hand side you can add chloride ions in the form of HCl and that will shift it to the right, add more water to shift it to the left, its an exothermic reaction so heat and it will shift to the left, cool and it will shift to the right... dont think u need to know much more
