A 50.0 mL sample containing Cd2 and Mn2 was treated with 40.4 mL
of 0.0500 M EDTA. Titration of the excess unreacted EDTA required
19.2 mL of 0.0300 M Ca2 . The Cd2 was displaced from EDTA by the
addition of an excess of CN–. Titration of the newly freed EDTA
required 18.2 mL of 0.0300 M Ca2 . What were the molarities of Cd2
and Mn2 in the original solution?
A biochemist has 100 mL of a buffered solution at pH 7.3. The
concentration of the buffer is 0.1 M, and the pKa of the
buffer is 7.8. If the biochemist adds 80 mL of a 0.1 N KOH solution
to the above buffered solution, what will be the final pH to the
nearest tenth of a unit?
