Definition: An Arrhenius base is a substance that when added to water increases the number of OH-ions in the water.Arrhenius bases follow the reaction:efinition: An Arrhenius base is a substance that when added to water increases the number of OH-ions in the water.
The Arrhenius Equation Background reading: Common sense and chemical intuition suggest that the higher the temperature, the faster a given chemical reaction will proceed. Quantitatively this relationship between the rate a reaction proceeds and its temperature is determined by the Arrhenius Equation.
