Whats a general rule for a strong base?

A general rule for identifying a strong base is that it typically contains hydroxide ions (OH⁻) and is often a metal hydroxide formed from an alkali or alkaline earth metal. Strong bases readily dissociate in water to produce a high concentration of hydroxide ions, resulting in a high pH. Common examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH). Additionally, bases with a strong affinity for protons, such as amines, can also be considered strong bases in certain contexts.
