Total number of moles of AgCl precipitated on addition of excess of AgNO 3 to one mole each of the following complexes Co NH 3 4 Cl 2 Cl , Ni H 2 O 6 Cl 2 , Pt NH 3 2 Cl 2 and Pd NH 3 4 Cl 2 is

Step-by-step solution

Silver nitrate on reaction of chloride ion gives silver chloride as precipitate. Chloride ions outside of coordination sphere will only give precipitates. Thus, Co NH 3 4 Cl 2 Cl ⇒ Gives 1 mole AgCl Ni H 2 O 6 Cl 2 ⇒ Gives 2 moles AgCl Pt NH 3 2 Cl 2 ⇒ Gives No AgCl Pd NH 3 4 Cl 2 ⇒ Gives 2 moles AgCl Total number of moles of AgCl = 5 mole.
