#### Solution Preview

The calculation should be in two parts.
In the first part, Strong base react with weak acid to form salt.Calculate the concentration of each using ICE table.
In the second part,use Henderson Hasselbalch equation to find the pH of new buffer.

Part-I :
When you add the NaOH solution to the buffer, it reacts with the NH4Cl to ...

#### Solution Summary

The solution determines the pH of the buffer.
