(a) A compound with formula RuCl3 . 5 H2O is dissolved inwater, forming a solution that is approximately the samecolor as the solid. Immediately after forming the solution,the addition of excess AgNO3(aq) forms 2 mol of solid AgClper mole of complex. Write the formula for the compound,showing which ligands are likely to be present in the coordinationsphere. (b) After a solution of RuCl3 . 5 H2O hasstood for about a year, addition of AgNO3(aq) precipitates 3mol of AgCl per mole of complex. What has happened inthe ensuing time?

Question

(a) A compound with formula RuCl3 . 5 H2O 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 AgNO3(aq) forms 2 mol of solid AgCl
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 RuCl3 . 5 H2O has
stood for about a year, addition of AgNO3(aq) precipitates 3
mol of AgCl per mole of complex. What has happened in
the ensuing time?
