Buffer Solution:A solution that resists changes in pH when acid or base is added to it. Buffers are typically made up of weak acids and their conjugate bases, or weak bases and their conjugate acids.
Conjugate Acid/Base Pair: When an acid loses its proton, it forms its corresponding base. Similarly, when a base accepts a proton, it forms its corresponding acid. These pairs are known as conjugate acid/base pairs.
Dissociation:The process by which compounds break apart into separate ions when dissolved in water.
