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 … WebDuring a titration, both the pH and volume of titrant are recorded. A plot of pH versus volume of titrant generates a titration curve (see graph 1 or 2). The actual equivalence point occurs at the mid-point of the sharp rise in the curve. In order to determine this point more accurately, a first derivative plot is prepared (see graph 3).

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: WebTitration curve end points are not as sharp as those for Total Chlorine. Therefore, the determination of Free Chlorine concentrations below 0.1 mg/L becomes problematic.
