Answer:
B. They Increase the [OH-]
Explanation:
Have a great day! :)
Taking into account the definition of the Arrhenius theory of acids and bases, the correct answer is option B. "Bases increase the concentration of hydroxide ions [OH⁻]"
An Arrhenius acid is defined as chemical substances that contain hydrogen, and that when dissolved in water produce a concentration of hydrogen ions or protons (H⁺), increasing the concentration of H⁺ in the solution.
That is, according to Arrhenius theory, an acid is a substance that dissociates H⁺ ions in aqueous solution.
On the other hand, according to this Theory, a Arrhenius base is any substance that, when dissolved, releases hydroxyl ions (OH⁻).
So, the correct answer is option B. "Bases increase the concentration of hydroxide ions [OH⁻]"
