In the titration of the weak acid (HA) by a strong base, the equivalence point is equal to the point at which HA is completely converted to A− (Option b).

What is the equivalence point?

The equivalence point refers to the point at which the titrant is enough to neutralize a given chemical solution.

Tiritation refers to a chemical analytical procedure where one chemical compound is determined by using another compound.

This process (Tiritation) is very common in analytical chemistry studies.

In conclusion, in the titration of the weak acid (HA) by a strong base, the equivalence point is equal to the point at which HA is completely converted to A− (Option b).
