If the freezing point of 0.01 molal aqueous solution of a cobalt (III) chloride-ammonia complex (which behaves as 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))

Answer»


Solution :`((DeltaT_(f))_(obs))/((DeltaT_(f))_(CAL))=i=3` which shows
`[Co(NH_(3))_(5)Cl]Cl_(2) to [Co(NH_(3))_(5)Cl]^(2+)+2Cl^(-)`
