Acids/Bases. Svante Arrhenius, a Swedish chemist, proposed the following definition: Acids form hydronium ions in aqueous solutions, while bases form hydroxide ions. Acids give off H + Bases give off OH -. Properties of acids. Give foods a tart or sour taste Electrolytes
H2O H2O H3O+ OH-
hydronium ion hydroxide ion
Water self ionizes to the concentration of 1.0 x 10-7 mol/L.
When the concentration of each ion equals 1.0 x 10-7 mol/L
the solution is said to be neutral
Therefore, since water is considered neutral the
concentrations of the ions can be calculated through the
Ion product constant.
