Answer & Solution

Correct Answer

(D) \(75\)

Step-by-step Solution

Detailed explanation

Isotonic solutions, \(\pi_{ K _2 SO _4}=\pi_{ Glucose }\) \(i \times 0.004 \times RT =0.01 \times RT\) \(i =2.5\) For \(K _2 SO _4 \quad\{\) for dissociation \(i =1+( n -1) \alpha\}\) \(\operatorname{DOD}(\alpha)=\frac{ i -1}{ n -1}=\frac{2.5-1}{3-1}=0.75\) \(\%\) dissociation…
