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?

ASSIGNMENT 7
1. Consider three hypothetical ionic solids: AXAX, and AX. (each X forms X). Each of these
solids has the same Ksp value, 5.5 x10'. You place 0.25 mol of each compound in a separate
container and add enough water to bring the volume to 1.0 dm' in each case.
a. Write the chemical equation for each of the solids dissolving in water.
b. Would you expect the concentration of each solution to be 0.25M in the compound?
Explain, in some detail, why or
c. Would you e
uexpect the concentrations of the A cations (A", A", and A") in the three
solutions to be the same? Does just knowing the stoichiometry of each reaction help you
determine the answer, or do you need something else? Explain your answer in detail, but
without doing any arithmetic calculations.
d. Of the three solids, which one would you expect to have the greatest molar solubility?
Explain in detail, but without doing any arithmetic calculations.
e. Calculate the molar solubility of…
