3. What do the solubility rules tell you about the way to separate the second group of cations? How can you tell each of the ions in this group apart? Think about changing the temperature and |

the pH. Design your own qualitative schenre for identification of these four Group II ions and

write it below. Experiment with each of the four ions alone and then in combinations. Test an

unknown to see if you can really determine the presence or absence of each of the four ions in

this group
