Select all of the following that are benefits of a pH titration that is monitored using a pH electrode.
a. The titration does not have to be stopped exactly at the equivalence point.
b. An accurate visual indicator is not necessary.
c. It's cheaper to run because no expensive equipment is needed.
d. You can visually determine the equivalence.
e. The identity of the analyte can usually be determined from the pH at the midpoint.
f. Less chemicals are needed since you do not titrate to the equivalence point.
