In the lecture we used titration of sodium carbonate with hydrochloric acid as an example to explain how to titrate a weak base with a strong acid. Suppose that you are using HNO3 to titrate Na3PO4, describe how to calculate pH at following different titration stages: (a) before titration (b) at 19 equivalence point (c) at 3rd equivalence point (d) between 2nd and 3rd equivalence points (e) after 3rd equivalence point Calculation is not required, simply write the...

Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...

Acid-Base Titration of a Weak Acid with a Strong Base: Determination of K. Introduction: You will be titrating a solution of a weak acid with 0.100 M NaOH, while monitoring the reaction using a pH meter. Weak acids have characteristic acid-ionization constants, K. The purpose of this lab is to use the titration to determine the value of this constant for the weak acid called “benzoic...
