MCQ
In which case van't Hoff factor is maximum $($assuming no hydrolysis$)\ ?$
- A$\text{KCl}, 50\%$ ionised
- B$\mathrm{K}_2 \mathrm{SO}_4, 40\%$ ionised
- ✓$\mathrm{FeCI}_3, 30\%$ ionised
- D$\mathrm{SnCI}_4, 20\%$ ionised
✓
Answer
Correct option: C.
$\mathrm{FeCI}_3, 30\%$ ionised
Soluten $a_ i = [1 + (n -1)a]$
$\text{KCl}\ 20.51.5$
$\mathrm{K}_2 \mathrm{SO}_4\ 30.41.8$
$\mathrm{FeCI}_3\ 40.31.9$
$\mathrm{SnCI}_4\ 50.21.8$
$\text{KCl}\ 20.51.5$
$\mathrm{K}_2 \mathrm{SO}_4\ 30.41.8$
$\mathrm{FeCI}_3\ 40.31.9$
$\mathrm{SnCI}_4\ 50.21.8$
