Arrhenius base

An Arrhenius base is a substance that increases the concentration of hydroxide ions (OH⁻) in water. In simpler terms, when you dissolve an Arrhenius base in water, it produces more of these hydroxide ions, which can make the solution more alkaline or basic. A common example of an Arrhenius base is sodium hydroxide (NaOH), often used in cleaning products. The key aspect is that it must be able to release hydroxide ions when mixed with water, contributing to the solution's basic properties.
