At the Oak Ridge National Laboratory in Tennessee, soils are heavily contaminated with mercury (Hg+2). In some of the soils, sulfate-reducing bacteria are producing bisulfide (HS'). In these soils, mercury precipitates with sulfide to form metacinnabar (HgS(). -2 HgS +H +Hg +HS (3), a. What is the equilibrium constant for this reaction? Assume a temperature of 25 °C. b. What is the effective equilibrium constant for an ionic strength of 0.01 M (call it Keeff)? Use the Davies equation to make the calculation
