Summary 6

You can end up with a buffer with two different ways:

1. When you want to make a buffer with a specific pH: When you want to obtain a buffer with a pH you just have to use the equation and change it with different bases and its pKa to adjust them to the pH that is needed.

2. When you end up with one by accident: This happens when you mix a weak acid with a strong base or a strong acid with a weak base, this happens particularly in a trituration.
