Pipette 100.0 mL of solution into a 150 mL beaker.
Add about 50 mL of DI water.
Place beaker onto magnetic stirrer, insert electrodes, switch on millivoltmeter and note the potential difference.
Add 0.02 M silver nitrate in 0.5 mL increments, noting the potential difference after each addition.
Continue for 2 mL beyond the point where the largest change in potential differenceoccurs.
The titration figure is taken as the average of the two values between which the largest
