Results Interpretation

Remember to record down the pH values from the pH meter shown in Part I and II. Be sure to also record the initial pH values of arginine before addition of HCl and NaOH. (This initial pH need not to be tabulated).

Take note of the volume of HCl and NaOH added (ml). You need this information to determine total volume (accumulate) added into the titration.

Then, download the following spreadsheet and input the recorded values.
