which of the following coordination compounds will most likely form a precipitate when treated with an aquesous solution of silver(l) nitrate?
i think its either a or b but i don't know which exactly is right?
Pick the one in which the Cl is not part of the coordination sphere with Cr.
that would be choice B right?
right. If the Cl is coordinated, it is a covalent bond and the covalent bonds doesn't allow the pptn of AgCl easily. Sometimes one can see a light cloudy color but not much. Outside the coordination sphere it is an ionic compound and the Ag^+ + Cl^- ==> AgCl proceeds easily.
