Acids and Bases Mastery

What are the common properties of strong acids?

• Strong acids do not conduct electricity.

• Strong acids are neutral in reaction with bases.

• Strong acids completely dissociate in water, have low pH, conduct electricity well, and react vigorously with bases and metals.

• Strong acids have high pH levels.

Name three examples of strong acids.

• Acetic acid, hydrochloric acid, hydrofluoric acid

• Hydrochloric acid, sulfuric acid, nitric acid

• Carbonic acid, phosphoric acid, nitric acid

• Phosphoric acid, both hydrogens from sulfuric acid, and hydroponic acid

What is the pH range of strong acids?

• 8 to 10

• 4 to 7

• 11 to 14

• 0 to 3

Describe the ionization process of a weak acid in water.

• A weak acid ionizes in water to form a strong base and water.

• A weak acid does not ionize in water at all, remaining entirely as undissociated molecules.

• A weak acid partially ionizes in water, establishing an equilibrium between the undissociated acid and its ions.

• A weak acid completely dissociates in water, producing only ions.

What is the significance of the acid dissociation constant (Ka)?

• The significance of the acid dissociation constant (Ka) is that it indicates the strength of an acid in solution.

• It measures the temperature of an acid solution.

• It indicates the color change of an acid in a reaction.

• It determines the solubility of an acid in water.

List two properties of strong bases.

• They partially dissociate in water.

• They have a low pH (usually below 7).

• They are always liquid at room temperature.

• 1. They completely dissociate in water. 2. They have a high pH (usually above 12).

How does the strength of an acid relate to its ability to donate protons?

• The strength of an acid is directly related to its ability to donate protons; stronger acids donate more protons.

• Weaker acids donate more protons than stronger acids.

• The strength of an acid is unrelated to proton donation.

• Stronger acids have fewer protons to donate.

What is the relationship between weak acids and their conjugate bases?

• Weak acids completely dissociate in solution.

• Conjugate bases are only formed from strong acids.

• Weak acids do not have conjugate bases.

• Weak acids and their conjugate bases are related through the equilibrium established during partial dissociation, where the conjugate base is formed when the weak acid donates a proton.

How do strong bases differ from weak bases in terms of dissociation?

• Both strong and weak bases dissociate equally in solution.

• Weak bases fully dissociate in solution, while strong bases do not.

• Strong bases only dissociate in acidic solutions.

• Strong bases fully dissociate in solution, whereas weak bases only partially dissociate.

Explain how the concentration of a weak acid affects its degree of ionization.

• Higher concentrations of weak acids lead to complete ionization.

• The degree of ionization decreases as the concentration of a weak acid decreases.

• The degree of ionization remains constant regardless of the concentration of the weak acid.

• The degree of ionization increases as the concentration of a weak acid decreases.
