In the titration of the weak acid (ha) by a strong base, such as naoh, what is meant by the equivalence point? select one:
a. the point at which the concentration of ha is equal to the concentration of a−.
b. the point at which ha is completely converted to a−.
c. the point at which the titration should be stopped.
d. the point at which ha begins to be converted to a−.

The point at which the titration should be stopped.

Explanation:

For any titration the equivalence point is when the number of equivalents of acid and base are equal.

Or

When the number of equivalence of hydrogen and hydroxide ions are equal.

At this point we should stop the tiration.

The reaction of weak acid and NaOH will be:

At equivalence point the

So after this we can do our calculations of the experiment hence should stop the titration.
