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