CHEM 404 Lecture Notes - Lecture 6: Buffer Solution, Conjugate Acid, Weak Base
Document Summary
03/26/19: acetic acid is a weak acid, this means that it is a substance whose dissociate is low. When a substance that forms a lower amount of ions when water, it is weak. Hydrochloric acid is a strong acid since it can dissociate completely when it is dissolved in water. In a buffer solution two species must be present a weak base or a weak acid and its respective salt. A buffer solution can regulate the changes in ph when an acid is added to a conjugate base. A solution of ch3cooh (weak acid) and ch3coo-(conjugate base), the acetic acid will dissociate as follows: When a strong acid is added, this substance provides h+ ions to the solution which react with the conjugate base. In this case, the ch3cooh- ions are produced by this reaction: When a strong base was added, this substance provides oh- ions which react with the acid.
