What Is a Base in Chemistry? Definition and Examples
A strong base is a compound that fully dissociates into its ions in aqueous solution. A weak baseincompletely dissociates into its ions, so that the resulting aqueous solution contains weak base, its conjugate acid, and water. Strong base: BOH + H2O → B+(aq) + OH–(aq) Weak base: BOH + H2O ↔ … See more
