In this lesson you will review the properties of acids and bases, define and identify acid-base pair conjugates and use the ion-product constant (self-ionization) of water to solve problems involving concentration of hydronium and hydroxide ions in aqueous solutions.
By the end of this students should be able to:
- list the properties of acid and bases.
- identify acid-base pair conjugate in reversible reactions.
- define how water self-ionizes and calculate the concentration of hydronium H3O+ ions and hydroxide OH– ions in aqueous solutions.
- determine the acidity of aqueous solutions using the water ion-product constant equation.
- define the concept of pH and the pH scale and establish the relationship between pH, pOH and pKw.
- solve problems involving [H3O+ ] and [OH–], pH and pOH ions in aqueous solutions.
