Sentences with «acid base» To add half reactions they must both be balanced with either acid or base. However, with some buffers, changes in concentration have more effect on dissociation, and stock solutions cannot be diluted without significantly affecting pH. Give the chemical equation. Human bodies contain a variety of organic and inorganic compounds, among those dicarboxylic acids play an essential role in many biological behaviors.
