Weba buffer. A weak base and some strong acid can also form a buffer. 2. Titration: A carefully measured neutralization. Since volumes are measured, this is a “volumetric analysis.” HA + OH- H 2 O + A-A “half-titration” (neutralizing half the acid or base) forms a buffer. In that case the pH = pK a 3. Equivalence Point: WebA titration curve can be used to determine: 1) The equivalence point of an acid-base reaction (the point at which the amounts of acid and of base are just sufficient to cause complete neutralization). 2) The pH of the solution at equivalence point is dependent on the strength …
