0.02 mole of `[Co(NH_(3))_(5)Br]Cl_(2) and 0.02" mole of "[Co(NH_(3))_(5)Cl]SO_(4)` are present in 200 cc of a solution X. The number of moles of the precipitates Y and Z that are formed when the solution X is treated with excess silver nitrate and excess barium chloride are respectively

Text Solution

Verified by Experts

The correct Answer is:
0.04
When excess of `AgNO_(3)` and `BaCl_(2)` are added to solution X.
`[Co(NH_(3))_(5) Br]Cl_(2) + 2AgNo_(3) to underset(1 "mol")[Co(NH_(3))_(5) Br](NO_(3))_(2) + underset(2 mol, 0.02 xx 2 = 0.04 mol)(2AgCl(ppt.Y)`
