WebA titration curve graphically depicts buffer capacity. The middle of the curve is flat because the addition of base or acid has little effect on the pH of the solution. This is known as the buffer zone. When a small amount of acid or base is added to the buffer system, the curve will increase dramatically once it exits the buffer region. Webtitration curve. The pH initially increases as we add base to the solution because the base deprotonates some of the positively charged H3N+CH2CO2H ions that were present in the strongly acidic solution. The pH then levels off because we form a buffer solution

WebA titration curve is a plot of some solution property versus the amount of added titrant. For acid-base titrations, solution pH is a useful property to monitor because it varies predictably with the solution composition and, therefore, may be used to monitor the titration’s progress and detect its end point.
