Water sometimes ionizes, a single molecule breaking apart into a hydrogen ion and a hydroxide ion. Other materials may dissociate in water, resulting in an increase of either (1) hydrogen ions or (2) hydroxide ions in the solution. We call the results
A) (1) acids and (2) bases.
B) (1) bases and (2) acids.
C) (1) neutral solutions and (2) neutronic solutions.
D) (1) hydrogen solutions and (2) hydroxide solutions.
