Alkali Salts
Alkali salts are soluble hydroxides of alkali metals and alkali earth metals, of which common examples are:
- Sodium hydroxide (often called "caustic soda")
- Potassium hydroxide (commonly called "caustic potash")
- lye (generic term, for either of the previous two, or even for a mixture)
- Calcium hydroxide (saturated solution known as "limewater")
- Magnesium hydroxide is an example of an atypical alkali since it has low solubility in water (although the dissolved portion is considered a strong base due to complete dissociation of its ions).
