\(\text { If a compound } \mathrm{X}_3 \mathrm{Y} \text { is } 60 \% \text { ionised in aqueous medium, what is its van't Hoff factor value? }\)
- A 3.1
- B 0.8
- C 0.6
- D 2.8
Answer & Solution
Correct Answer
(D) 2.8
Step-by-step Solution
Detailed explanation
The compound \(X_3Y\) dissociates in aqueous medium as follows: \(X_3Y \rightarrow 3X^{+} + Y^{3-}\) The number of ions produced per formula unit is \(n = 3 + 1 = 4\). The degree of dissociation is given as \(\alpha = 60\% = 0.6\). The van't Hoff factor \(i\) is calculated using…
