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

Answer»


Solution :`underset(n_(1)=2)(2AgNO_(3))+[Cr(H_(2)O)_(5)Cl]Cl_(2)to [Cr(H_(2)O)_(5)Cl](NO_(3))_(2)+2AgCl`
`(M_(1)V_(1))/(n_(1))=(M_(2)V_(2))/(n_(2))`
`(0.1xxV)/(2)=(0.01xx30)/(1)`
V=6 mL
