Unformatted text preview: perform some precipitation because HgOH has a small Ksp value. In the other hand, the unknown solution did not form out the precipitation, so there are no Hg2 ions in the unknown solution. In the part four, the solution forms out the precipitation because the AgNo3 has a smaller Ksp value. The result reach my expectation. Also, I found there are Pb and Ag ions in the unknown solutions. Conclusion: The cations in the unknown #2 solution are the Pb and Ag ions. Questions: 1. A. NH4OH B. HCl C. K2CrO4 D. has different color. 2. (Cl-) + (Ag+) ----- AgCl (s) AgCl + (NH4+)---- Ag(NH3)2 + 3. Part 1: Pb+Cl---PbCl Ag+ Cl--- AgCl Hg + ClHgCl Part2: Pb + CrO4 --- PbCrO4 Part 3: Ag + NH4--- Ag(NH3)2+ Hg+ Cl + NH$--- HgNH2Cl5 Part 4: Ag(NH3) ---- AgCl...
