How do you know if something is an alkali just by the name?

You can identify an alkali by its name if it contains specific terms or elements associated with alkalis. Typically, alkalis are hydroxides of alkali metals (like sodium or potassium) or alkaline earth metals (like calcium). If the name includes "hydroxide," such as sodium hydroxide (NaOH) or potassium hydroxide (KOH), it indicates an alkali. Additionally, the presence of alkali metal names in the formula or common names suggests it is an alkali, such as sodium or potassium compounds.
