The ingestion of lead from food, water, or other environmental source can lead poisoning, a serious condition that affects the central nervous system, causing symptoms such as distractibility, lethargy, and loss of motor function. Lead poisoning treated with chelating agents, substances that bind to lead and allow it to be eliminated in urine. A modern chelating agent used for this purpose is succimer (C 4 H 6 O 4 S 2 ) suppose you are trying to determine the appropriate dose for succimer treatment of lead poisoning. Assume that a patient’s blood lead levels are 0.550 mg/L, that blood volume is 5.0 L, and that 1 mol of succimer binds 1 mol of lead. What minimum mass of succimer in milligrams is needed to bind all of the lead in this patient’s bloodstream?

Many waste water treatment facilities have strict guidelines on the amounts of transition metals that can be discharged
into the sewer systems. This creates a waste disposal problem since student experiments in general chemistry courses can
generate large volumes of aqueous wastes containing high concentrations of some of these transition metals. In the
CHEM 120 lab, we have generated a large amount of aqueous copper containing waste.
At this point, the waste solution contains the aqueous copper species, Cu(H20)+, recall that in aqueous solution the first-
row transition metals exist as the aquated ions, for simplicity we often abbreviate these as Cu?+ (ag).
A cost-effective method for removing copper from aqueous solution is to precipitate the ions using a source of sulphide
ion, S. By adding sodium sulphide (NazS) to the waste solution, we should be able to precipitate copper as copper
sulphide and subsequently remove it by filtration:
Cu? (aq) + S (aq) → CuS(aq)
(The Ksp for CuS =…
