Unit 11 BR #6: Acid Base Theory and the pH Scale

According to Arrhenius acid-base theory, an acid ___.

• is an H⁺ acceptor

• is a H⁺ donor

• is a substance that produces H⁺ in water

• turns litmus paper blue

NaOH is:

• an Arrhenius acid

• neither an acid nor a base

• both an acid and a base

If a solution is basic which ion will be more present?
