4.2.5 Strong and weak acids

Cards (28)

  • What is a strong acid?
    Substance that completely dissociates
  • Weak acids release a lower concentration of hydrogen ions compared to strong acids.

    True
  • Steps in the ionization process of an acid
    1️⃣ Dissolving the acid in water
    2️⃣ Acid dissociates into ions
    3️⃣ Hydrogen ions are released
  • The degree of ionization measures the extent to which an acid dissociates into ions
  • What is the degree of ionization for weak acids?
    Partial
  • Strong acids completely ionize in water, while weak acids only partially ionize
  • What degree of ionization do strong acids have?
    Complete ionization
  • Match the pH range with the acid type:
    Very low (0-2) ↔️ Strong Acids
    Low (3-6) ↔️ Weak Acids
  • Acetic acid is an example of a weak acid.
    True
  • Hydrochloric acid (HCl) is an example of a strong acid
  • Weak acids release a lower concentration of H+ compared to strong acids.

    True
  • What is the key difference in the degree of ionization between strong and weak acids?
    Complete vs. Partial
  • The degree of ionization determines the pH of a solution.

    True
  • Acetic acid is an example of a weak acid, while hydrochloric acid is a strong acid
  • Strong acids release a high concentration of hydrogen ions (H+) when dissolved in water
  • Match the acid type with its example:
    Strong acid ↔️ Hydrochloric acid (HCl)
    Weak acid ↔️ Acetic acid (CH3COOH)
  • Strong acids fully ionize in water, while weak acids only partially ionize.
    True
  • What is the degree of ionization for strong acids?
    Complete
  • What type of ionization do weak acids have?
    Partial ionization
  • The degree of ionization determines the concentration of hydrogen ions in a solution.

    True
  • Lower pH values indicate stronger acids with higher [H+]
  • What is the pH range of strong acids?
    0-2
  • What happens to strong acids when dissolved in water?
    They completely dissociate
  • What happens to weak acids when dissolved in water?
    They partially dissociate
  • Match the property with the acid type:
    Complete Dissociation ↔️ Strong Acids
    Partial Dissociation ↔️ Weak Acids
  • Strong acids release a high concentration of hydrogen ions, while weak acids release a lower concentration
  • What does the pH range of weak acids indicate about their hydrogen ion concentration?
    Lower hydrogen ion concentration
  • Strong acids release a higher concentration of H+ ions than weak acids.
