Of the following statements regarding Mohr's salt experiment,
the incorrect one is:
Select one:
a.
At the equivalence point of the titration, a dramatic change in
potential occurs with the addition of a small amount of
titrant.
b.
The equivalent volume of the titration can be determined from the
plot of E versus volume of titrant.
c.
The equivalent volume of the titration can also be determined from
the plot of the first derivative of the potential versus the
average volume of the titrant.
d.
The end point of the titration is obtained when the indicator
changes from violet to greenish yellow.
and.
The equivalent volume can be determined as the one in which the
value of Y” is equal to 0.
