Follow the first 5 steps systematic method in the problem below. You do not need to do step 6. Determine the solubility of HgBr2, a sparingly soluble salt, in the presence of 0.0010 M NH3. NH3 is a weak base that reacts with Hg2+ in the reaction Hg2+ + 4NH3 (aq) ↔ Hg(NH3)42+. For this problem, you can ignore the effects of ionic strength and also assume that no other metal-ligand complexes form.
