Calculate the value of van't Hoff factor...

Calculate the value of van't Hoff factor for a dilute solution of `K_(2)SO_(4)` in water.

Text Solution

Verified by Experts

The correct Answer is:
3
`K_(2)SO_(4)` being salt is strong acid and strong base is expected to be completely dissociated in water as,
`K_(2)SO_(4) rarr 2K^(+) + SO_(4)^(2-)`
Now, `alpha = (i-1)/(n-1)`
`because alpha = 1` and `n = 3`
`:. 1=(i-1)/(3-1) rArr i=3`
