एक विलेय (70%) चतुर्मेर बनाता है। यदि सामान्य हिमांक अवनमन (0.80,K) है तो देखा गया हिमांक अवनमन कितना होगा?
A solute undergoes (70%) tetramer association. If the normal freezing point depression is (0.80,K), what will be the observed freezing point depression?
Explanation opens after your attempt
B. (0.38,K)
Concept
चतुर्मेर के लिए \(i=1-\alpha+\frac{\alpha}{4}\)। / For tetramerisation \(i=1-\alpha+\frac{\alpha}{4}\).
Why this answer is correct
\(i=1-0.70+\frac{0.70}{4}=0.475\)। / \(i=1-0.70+\frac{0.70}{4}=0.475\).
Exam Tip
\(देखा गया अवनमन (0.475\times0.80=0.38\),K) होगा। \(/ Observed depression (=0.475\times0.80=0.38\),K).
