Summary:
- An Arrhenius base is a compound, which ionizes to yield hydroxide ions (OH−) in aqueous solution.
- Table below lists several of the more common bases.
- All of the bases listed in the table are solids at room temperature.
- Upon dissolving in water, each dissociates into a metal cation and the Hydroxide ion.
- Compounds of the Group 2 metals (the alkaline earth metals) are also basic.
- These compounds are generally not as soluble in water.
