## Question:

Consider the titration of 50.0 mL of 0.45 M HCN with 0.25 M KOH. Calculate the pH before any KOH has been added.

## Weak Acids:

A weak acid is characterized by its incomplete dissociation in aqueous solution. The extent by which it dissociates can be quantified by using the percent ionization or acid dissociation constant. It is important to note that the percent ionization is dependent on the initial concentration.
