The solubility of picric acid at 20 degree C is 9.56 g per 100 g of benzene, and 1.4 g per 100 g of water. If industrial waste water contains 1000 mg/L of picric acid, what concentration would remain after 1 extraction with 1 kg of benzene for 1 kg of water?

I think the concentration will be zero in water. All absorbed by benzene??
Of course I am not sure. Would you please help me to find the right answer?

Dear kabir408;

Also your logic must tell you, that your answer must be wrong!

Use these links below to try the calculation for the distribution:
Extraction following:  "Solubility Problem (Extraction!)”,  –   and be surprised!

For the “Nernst Partition Law”, see on:   "Nernst Partition Law:  Absorption (chemistry)”.


Good Luck!
