The taste of lemons and lime, the bite of sourdough bread, and the tang of a tomato are all caused by acids. Acids may be defined as substances that produce H. +. ions in solution. Citric acid, acetic acid, and tartaric acid are shown here.. Topic 8.4. A. cids. w. hen a . STRONG. acid dissolves- all, or nearly all, of the acid molecules dissociate to produce H. +. . or H. 3.
