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

**Titration of a Weak Acid with a Strong Base**

**Problem:**
A 25.0 mL aliquot of 0.02 M HCNO (weak acid) is titrated with 0.15 M NaOH (strong base). Calculate the pH after the following additions of the base solution:
