Question

According to the Arrhenius definition, why is sodium hydroxide a base?

Answer 1

According to the Arrhenius definition, a base is a substance that ionizes in water to produce hydroxide ions (OH-). Sodium hydroxide, which has the chemical formula NaOH, is a base because when dissolved in water, it dissociates into sodium ions (Na+) and hydroxide ions (OH-). Since it produces hydroxide ions in water, it is classified as a base according to the Arrhenius definition.
