A decimolar solution of potassium ferroc...

A decimolar solution of potassium ferrocyanlde `K_(4) [Fe(CN)_(6)]` is 50% dissociated at 3001K. Calculate the value of Van't Hoff factor for postuslum ferrocyanide.

Text Solution

Verified by Experts

Vant Hoff factor `" " (i) = ("Normal molar mass ")/("Abnormal molar mass") `
`alpha = (i-1)/(n-1)`
`(50)/(100) = (i-1)/(5-1)`
`i-1 = 4 xx 0.5 `
`i-1 = 2`
i=3
