Question

Lead poisoning is a serious condition resulting from the ingestion of lead in food, water, or other
environmental sources. If affects the central nervous system, leading to a variety of symptoms such as
distractibility, lethargy, and loss of motor coordination. Lead poisoning is treated with chelating
agents, substances that bind to metal ions, allowing them to be eliminated in the urine. A modern
chelating agent used for this purpose is succimer (C4H6O4S2). suppose you are trying to determine the
appropriate dose for succimer treatment of lead poisoning. What minimum mass of succimer (in mg)
is needed to bind all of the lead in a patient

Explanation / Answer

total blood in patient body = 50 deciliters

So total lead = 45*10^-6*50 = 0.00225 g

moles of lead = 0.00225/207 =1.08696*10^-5 moles

SO moles of succimer =1.08696*10^-5 moles

mol wt of succimer = 182 g/mol

So mass of succimer = 1.97*10^-3 g of succimer
