Acid Base Titration
An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.
Question
100%

A 10.0 mL solution of 0.330 M NH, is titrated with a 0.110 M HCI solution. Calculate the pH after the following additions of the HC1 solution: 0.00 mL,
10.0 mL, 30.0 mL, and 40.0 mL. Round your answer to 3 decimal places.

Note: Reference the Ka of acids at 25 °C and Kb of bases at 25 °C tables for additional information.
