At Half Equivalence Point?

At Half Equivalence Point?

The half equivalence point represents the point at which exactly half of the acid in the buffer solution has reacted with the titrant

titrant
In 1828, the French chemist Joseph Louis Gay-Lussac first used titre as a verb (titrer), meaning "to determine the concentration of a substance in a given sample". Volumetric analysis originated in late 18th-century France.

. The half equivalence point is relatively easy to determine because at the half equivalence point, the pKa of the acid is equal to the pH of the solution.

Is half equivalence point half of equivalence point?

This point – called the equivalence point – occurs when the acid has been neutralized. The half-equivalence point is halfway between the equivalence point and the origin. This is the point at which the pH of the solution is equal to the dissociation constant (pKa) of the acid.

What is equal at the equivalence point?

The point at which the number of moles of added base are equal to the number of moles of acid in the analyte solution is called the equivalence point. It is easy to identify this point in a titration because it is the volume at which the pH is rapidly changing.
