A solution is known to contain Bi3+ ion or Cd2+ ion or both. Describe the test(s) that could be used to seperate and identify these ions. Describe the results you would expect to see for each ion, if that ion were present.
Draw a graph that shows the relative energy of the conformer as a function of the torsional angle. Make sure that you clearly label which conformer corresponds to which position on the graph.
