A six co-ordinate complex has the formula `CoCl_(3).5NH_(3).H_(2)O`. Electrical coductance measurements indicate the presence of three ions in one formula unit. How many moles of `AgCl` will be percipated with excess `AgNO_(3)` solution with two mole of complex?

Text Solution

Verified by Experts

The correct Answer is:
1
`[overset(III)(Co)(NH_(3))_(5) Cl]Cl_(2). H_(2)O (aq) hArr [overset(III)(Co) (NH_(3))_(5) Cl]^(2+) (aq) +2Cl^(-) (aq)`
`2Ag^(+)+2Cl^(-) rarr 2AgCl darr ("white")`
