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...

    It's a weak acid strong base titration 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...

    can someone please help me out with questions 1-5, please To add more information this was given to me for a lab that used a weak acid and we added a strong base through titration. We just observed how the ph changes. Later we then used a buffer with a weak acid to see how buffers affect ph change. These questions are basically surrounded around those topics to help us prepare. However, I'm kinda confused about answering them because weak...
