(d(i))[2]
Identify the two possible cations that the observations in test 2 indicate could be present in solid K.
(d(ii))[2]
Describe an additional test that can be carried out on solution K to confirm which one of the two cations identified in (d)(i) is present in solid K. Explain how the outcome of this test shows which of these two cations is in solid K.
