Consider the phase transfer catalyst, dimercaprol (C3H8S2O, structure shown below).
a. Write out the chemical equation for the binding of this metal chelator to Hg2+.How would this equation differ if it was binding to Ag+ instead?
b. If you wanted to keep Hg2+ in the organic phase, would you select a high or low pH? Explain.
c. If you wanted to keep Hg2+ in the aqueous phase, would you use a high or low concentration of dimercaprol? Explain.
