web.gccaz.eduAcid-Base Titration Curves Using a pH Meter Introduction: In this experiment you will use a pH sensor to collect volume and pH data as you titrate two acids with sodium hydroxide. You will obtain titration curves for the following combinations of acids and bases (exact concentrations
Using Graphical Analysis in Titration Curves
www.ccri.eduUsing Graphical Analysis in Titration Curves A typical titration curve obtained by plotting the measured pH of a weak acid solution as a strong base is added using graphical analysis for Windows is illustrated as follows: The equivalence point is halfway up the vertical portion of the curve, about 27 mL for this titration.
Experiment 17: Potentiometric Titration
www.bc.eduExperiment 17: Potentiometric Titration Objective: In this experiment, you will use a pH meter to follow the course of acid-base titrations. From the resulting titration curves, you will determine the concentrations of the acidic solutions as well as the acid-ionization constant of a weak acid.

dpuadweb.depauw.edu9A.3 Titration Curves To find a titration’s end point, we need to monitor some property of the reaction that has a well-defined value at the equivalence point. For example, the equivalence point for a titration of HCl with NaOH occurs at a pH of 7.0. A simple method for finding the equivalence point is to monitor the

EXPERIMENT 1 ACID BASE TITRATION - UM
kimia.um.edu.myACID BASE TITRATION Objective : To determine pH curve for titration of strong acid-strong base and weak acid-strong base. 1 Theory The process of adding acid to a base (or vice versa) to produce a salt and water is called neutralization. In the neutralization of hydrochloric acid with sodium hydroxide, the reaction that occurs is:
