Problem 68 AE
(a) A compound with formula RuC13 • 5 H20 is dissolved in water, forming a solution that is approximately the same color as the solid. Immediately after forming the solution, the addition of excess AgN03(ag) forms 2 mol of solid AgCI per mole of complex. Write the formula for the compound, showing which ligands are likely to be present in the coordination sphere, (b) After a solution of RuC13 • 5 H20 has stood for about a year, addition of AgN03(aqi) precipitates 3 mol of AgCI per mole of complex. What has happened in the ensuing time?
