Give an example of a strong acid.

• Hydrochloric acid (HCl)

• Nitric acid (HNO3)

• Sulfuric acid (H2SO4)

• Acetic acid (CH3COOH)

Provide an example of a weak base.

• Sodium hydroxide

• Hydrochloric acid

• Ammonia (NH3)

Explain the ionization process of acids.

• The ionization process of acids involves the release of oxygen ions (O-)

• Acids do not undergo ionization when dissolved in water

• The ionization process of acids involves the release of sodium ions (Na+)

• The ionization process of acids involves the release of hydrogen ions (H+) when dissolved in water.

Describe the dissociation of bases.

• Dissociation of bases involves the release of hydroxide ions (OH-) into water.

• Dissociation of bases leads to the release of protons (H+).

• Dissociation of bases involves the release of hydrogen ions (H+).

• Bases dissociate by forming covalent bonds with water molecules.
