15.1 Exercise 45

What reagent might be used to separate the ions in each of the following mixtures, which are 0.1 M with respect to each ion? In some cases it may be necessary to control the pH. (Hint: Consider the K_sp values given in Appendix J.)

(a) $\text{Hg}_{2} ^{\text{2}+}$ and Cu²⁺

(b) $\text{SO}_{4} ^{\text{2}−}$ and Cl^–

(c) Hg²⁺ and Co²⁺

(d) Zn²⁺ and Sr²⁺

(e) Ba²⁺ and Mg²⁺

(f) $\text{CO}_{3} ^{\text{2}−}$ and OH^–
