A dilute solution of \(\mathrm{K}_2 \mathrm{HgI}_4\) reagent is \(95 \%\) ionised. What would be the approximate value of its van't Hoff factor?
- A \(2.05\)
- B \(1.85\)
- C \(1.50\)
- D \(2.90\)
Answer & Solution
Correct Answer
(D) \(2.90\)
Step-by-step Solution
Detailed explanation
The dissociation of \(\mathrm{K}_2\mathrm{HgI}_4\) in a dilute solution is represented as: \(\mathrm{K}_2\mathrm{HgI}_4 \rightarrow 2\mathrm{K}^{+} + \mathrm{HgI}_4^{2-}\) The number of ions produced per formula unit is \(n = 3\). The van't Hoff factor \(i\) is given by the…
