Objectives: This experiment aims at determining the concentration of acid-base equilibrium constants for acetic acid and aqueous ammonia using titration curves.  Introduction: The main objective in the volumetric titration of an acid with a base is the determination of the equivalence point. The equivalence point is a point where the acid has been fully neutralized by the base. One can determine the completeness of the reaction by adding an indicator that changes when the reaction is approaching an equivalence point. Furthermore, the completeness of a reaction can be determined by a pH meter. A pH meter measures the actual pH of the solution during titration.  pH titration curves: In titration curves of a weak acid or a weak base, the equivalence point lies at the midpoint of particular two points. Equivalent point is the inflection point on the titration curve between these points. Once the equivalence point is established, the volume of a titrant used ca...

The result section of a chemistry lab report is where you present your results. You can present your results in the form of tables, graphs, and diagrams. Tables, graphs or diagrams must be labeled correctly. You can write a brief description on either top or below of the tables, graphs, and diagrams. However, labeling of your tables and figures depend on the instructions provided by your institution. In addition, you have to briefly describe your results. Though, you should not explain your results in this section. The explanation of your results should be in your discussion part.    Let us check a few examples:  Example 1 An experiment was conducted to determine the concentrations and the acid-base equilibrium constants for acetic acid and aqueous ammonia using titration curves. During the lab session, the following raw data for titration of an acetic acid with sodium hydroxide, and titration of aqueous ammonia with hydrochloric acid, CLICK HERE TO FIN...
