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...

Advanced Chemistry with Vernier Buffers 4. Buffer capacity is usually defined as the pKa Il pH unit- that is, the pH range over which the ratios of protonated to unprotonated form of the buffer go from 10:1 to 1:10.

How would we find the net ionic equation for this?
For part 4, I mean.
Obtain about 15 ml. of 1.0 M acetic acid in a clean, dry, small plastic beaker. Measure 5.00 mL of the 1.0 M CH,COOH solution in a 10-mL graduated cylinder and transfer it to a 50-mL graduated cylinder. Add enough distilled water to have a total volume of 50.0 mL and mix it thoroughly. The result is a 0.10 M CH,COOH solution. Note and record...
