0.01 m aqueous solution of `K_(3)[Fe(CN)_(6)]` freezes at `-0.062^(@)C`. What is the apparent percentage of dissociation ? (`K_(f)` for water `= 1.86" K kg mol"^(-1)`)

Text Solution

Verified by Experts

The correct Answer is:
`0.78%`
`{:(DeltaT_(f) = iK_(f)m ,0.062 =ixx 1.86 xx 0.01),(i = 3.33 ,alpha = (i-1)/(n-1)),(alpha rArr (3.33-1)/(4-1) ,alpha rArr 0.777):}`
