You wish to undertake a 100 step countercurrent extraction of solutes A & B with distribution coefficients D. 22 &D; = 10. Suppose the volumes of mot and stationary are equal. It tractions 42.58 and 60-72 are each pooled find the recovery and purity of each solute. A A 92.5% recovery of 99.5% pure 3:67.6% recovery of 100 pure BA79.8% recovery of 99.7% pure A 3:52.0% recovery of 86.6% pure CA 18 recovery of 980 pure A recovery of 97.3. pure recovery of 970 pure A
