2. Write the balanced chemical equation for the neutralization of hypobromous acid with potassium hydroxide. Is the pH at the equivalence point above, below, or exactly 7? Explain. 3. Some pH meters are designed for a three-point calibration at pH 4, 7, and 10. Ours are only calibrated with a two-point procedure at 4 and 7 or 7 and 10. Which range would you expect we are calibrating them at for this experiment? Why? 4. (a)...

6-8: Acid-Base Titration: Practice Titrations provide a method of quantitatively measuring the concentration of an unknown solution. In an acid-base titration, this is done by delivering a titrant of known concentration into an analyte of known Although in this case you know the concentration of both NaOH and HCI, this will give you practice in performing a titration and calculating the concentration of the analyte, which in this case is HCI. 1.

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...

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...
