Mercury(II) hydroxide, Hg(OH)2, is so insoluble in water that only about 2 formula units per billion dissolve. It does, however, neutralize hydrochloric acid. Explain, with appropriate net-ionic equations, how the methods in this experiment can be used to obtain the enthalpy of solution for Hg(OH)2 even when direct measurements of that process is not possible.
