If the freezing point of a 0.01 molal aqueous solution of a cobalt(III) chloride-ammonia complex (which behaves as a strong electrolyte) is `-0.0558^(@)C` the number of chloride(s) in the coordination sphere of the complex is _________. [`K_(f)` of water = `1.86K kg "mol"^(-1)` ]

Text Solution

Verified by Experts

The correct Answer is:
1
`DeltaT_(f) = iK_(f)m`
`0.0558 = ixx 1.86 xx 0.01 rArr i=3`
Structure should be: `[Co(NH_(3))_(5)CI] Ci_(2)`
