The volume (in ml) of 0.10 M AgNO_(3) required for complete precipitation of chlorine ions present in 30 ml of 0.01 M solution of [Cr(H_(2)O)_(5)Cl]Cl_(2) as silver chlorine is close to __________

Answer»


SOLUTION :no. of moles of
`[Cr(H_(2)O)_(5)Cl]Cl_(2)=(0.01xx30)/(1000)=3xx10^(-4)` moles
`underset(?)underset(2)(AgNO_(3))+underset(3xx10^(-4))underset(1)([Cr(H_(2)O)_(5)Cl])Cl_(2)rarr2AgCl`
`IMPLIES 6xx10^(-4)=0.1xxV`
`V=6xx10^(-3)"lit "implies V=6ml`
