Question:
The drug Librium gives a polarographic wave with E1/2 = - 0.265 V (versus S.C.E.) in 0.05 M H2SO4. A 50.0-mL sample containing Librium gave a wave height of 0.37 μA. When 2.00 mL of 3.00 mM Librium in 0.05 M H2SO4 were added to the sample, the wave height increased to 0.80 μA. Find the molarity of Librium in the unknown.
