5. Discuss the effect of the pH and of the reagent concentration on the solvent extraction of metal chelates. What is the basis of accelerated solvent extraction? For a solute with a distribution ratio of 25.0, show by calculation which is more effective, extraction of 10 mL of an aqueous solution with 10-mL organic solvent or extraction with two separate 5.0-mL portions of organic solvent. Arsenic (III) is 70% extracted from 7 M HCl into an equal volume of toluene. What percentage will remain unextracted after three individual extractions with toluene?
