Question

he volume required to reach the equivalence point of an acid-base titration depends on the volume and concentration of the acid or base to be titrated and on the concentration of the acid or base used to do the titration. It does not, however, depend on the whether or not the acid or base being titrated is strong or weak. Explain.

Answer 1

the equivalence point occurs when the amount of added titrating substance is stoichiometrically equivalent to the present amount of the analyte or substance to be analyzed in the sample

Step-by-step explanation:

in the equivalence point, we have:

• moles of acid = moles of base

⇒ (Volume * Concentration )acid = (Volume * Concentration)base

As can be seen in the equation, at the point of quivalence there is complete salt formation, so the pH is calculated through the salt, therefore, it is not significant how strong or weak the base or acid is in the titration.
