Strong bases are bases which completely dissociate in water into the cation and OH-
(hydroxide ion). The hydroxides of the Group I and Group II metals usually are considered to be strong bases. Here is a list of the most common strong bases.
- LiOH - lithium hydroxide
- NaOH - sodium hydroxide
- KOH - potassium hydroxide
- RbOH - rubidium hydroxide
- CsOH - cesium hydroxide
- *Ca(OH)2 - calcium hydroxide
- *Sr(OH)2 - strontium hydroxide
- *Ba(OH)2 - barium hydroxide
* These bases completely dissociate in solutions of 0.01 M or less. The other bases make solutions of 1.0 M and are 100% dissociated at that concentration. There are other strong bases than those listed, but they are not often encountered.
