a. A compound with formula RuCl3 . 5H2O is dissolved in water,forming a solution that is approximately the same color as thesolid. Immediately after forming the solution, the addition ofexcess AgNO3 (aq) forms 2 mol of solid AgCl per mole of complex.Write the formula for the compound, showing which ligands arelikely to be present in the coordination sphere.
b. After a solution of RuCl3 . 5H2O has stood for about ayear, addition of AgNO3 (aq) precipitates 3 mol of AgCl per mole ofcomplex. What has happened in the ensuing time?
