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

Question

TestHub · Accepted Answer

Silver nitrate on reaction of chloride ion gives silver chloride as precipitate. Chloride ions outside of coordination sphere will only give precipitates. Thus,
$[Co {({NH}_{3})}_{4} {Cl}_{2}] Cl \Rightarrow$ Gives $1$ mole $AgCl$
$[Ni {(H_{2} O)}_{6}] {Cl}_{2} \Rightarrow$ Gives $2$ moles $AgCl$
$[Pt {({NH}_{3})}_{2} {Cl}_{2}] \Rightarrow$ Gives No $AgCl$
$[Pd {({NH}_{3})}_{4}] {Cl}_{2} \Rightarrow$ Gives $2$ moles $AgCl$
Total number of moles of $AgCl = 5$ mole.
