A 40.00-mL sample of 0.0500 M HNO2 is titrated with 0.0200 M Cs4+. The pH is held constant at 0. The potential is measured relative to the calomel electrode (E=0.241 V).
a. Write out the two ½ reactions, the net reaction and the Nernst equation in general form for this titration before the equivalence point.
b. What is the potential at the equivalence point and 2Ve (two times the volume required to reach the equivalence point)?
c. What is the potential at the equivalence point, if an AgCl electrode (E=0.199) is used as a reference electrode?
d. What indicator could be used to measure the endpoint for this titration?
