This project was preformed to supply Libretext authors with videos on General Chemistry topics which can be used to enhance their projects. Also, these videos are meant to act as a learning resource for all General Chemistry students . Video Topics In a buffer solution, the pH values change very slightly with the addition of an acid or a base. Buffers are used to control the pH of a solution. This video discusses how Le Chatlier's principal allows a buffer to uses use up any H 3 O + or – OH added to only provide a slight change to the pH.
