The volume (in mL) of 0.1 M AgNO_(3)required for complete precipitation of chloride ions present in 30 mL of 0.01 M solution of [Cr(H_(2)O)_(5)Cl]Cl_(2), as silver chloride is close to

Answer»


Solution :m MOLES of `[Cr(H_(2)O)_(5)CL]Cl_(2)=0.01xx30=0.3`
`RARR` m mole of `Cl^(-)=0.3xx2=0.6`
`rArr` m mole of `Ag^(+)` = m moles of `Cl^(-)`
`rArr 0.1xx V=0.6`
`rArr V=6 mL`.
