alkalis
High-pH substances
Alkalis are substances that neutralize acids, forming the chemical opposite of acidic compounds.
In chemistry, alkalis are bases that dissolve in water, producing hydroxide ions—common examples include lye, ammonia, and baking soda.
Solutions high in alkali feel slippery and taste bitter.
The soil here is too alkaline for blueberries.
Alkali is the singular form.
