In the determination of molar mass of `A^(+) B^(-)`, using a colligative property, what may be the value of van't Hoff factor if the solute is 50% dissociated ?

Explanation

`alpha=(i-1)/(n-1)rArr0.5=(i-1)/(2-1)rArri=1.5`.
Given `alpha=0.5`
Asked `i=?`
Formulae: `alpha=(i-1)/(n-1)`
Explanation: `alpha=` degree of dissociation, `i=` van't Hoff factor
Subsititution `&` calculation :
`0.5=(i-1)/(2-1)rArri=1.5`.
