Chapter 2: Problem 33
A solution contains a mixture of four different compound: \(\mathrm{KCl}(a q),\) \(\mathrm{Fe}\left(\mathrm{NO}_{3}\right)_{3}(a q), \mathrm{MgSO}_{4}(a q),\) and \(\mathrm{N}_{2} \mathrm{H}_{4}(a q) .\) Which of these compounds would be easiest to separate via distillation? (A) \(\mathrm{KCl}(a q)\) (B) \(\mathrm{Fe}\left(\mathrm{NO}_{3}\right)_{3}(a q)\) (C) \(\mathrm{MgSO}_{4}(a q)\) (D) \(\mathrm{N}_{2} \mathrm{H}_{4}(a q)\)
