1.7.12 pH Titration Curves - Save My Exams

WebThe results of an acid–base titration can be summarized using a titration curve, which plots pH vs. volume of titrant added. For the titration of a strong acid with a strong base, the curve begins acidic and then turns basic after the equivalence point, which occurs at pH = 7. Web14. The equivalence point occurs at the exact middle of the region where the pH rises sharply. Chances are there is no data point exactly at the equivalence point so it must be found graphically. Using a ruler and a pencil draw straight lines at the top and bottom of the the titration curve as shown in Figure 1b. hikma international pharmaceuticals llc

The volume is represented as an independent variable, while the pH is a dependent variable. WebThe titration curve is a graphical representation that depicts the correlation between the pH of a solution, typically an acid, and its corresponding volume. The indicator is employed to ascertain the endpoint of a titration, which is the point at which the quantity of base added is sufficient to neutralize all of the acid present in the solution. hikma jobs in columbus ohio
