Questions and Answers

What is the pH of a solution with a hydrogen ion concentration of $10^{-8}$ mol/L?

  • pH = 10
  • pH = 7
  • pH = 6
  • pH = 8 (correct)
  • What is the definition of a strong acid?

  • A strong acid almost completely dissociates in aqueous solution and produces many H+ ions. (correct)
  • A strong acid is a proton acceptor and does not produce H+ ions.
  • A strong acid partially dissociates in aqueous solution and produces few H+ ions.
  • A strong acid cannot dissociate in aqueous solution and does not produce H+ ions.
  • What is the definition of a buffer?

  • A solution that resists changes in pH when an acid or alkali is added to it. (correct)
  • A substance that increases the rate of a chemical reaction without being consumed in the process.
  • A substance that completely neutralizes acids to maintain a constant pH.
  • A solution that enhances changes in pH when an acid or alkali is added to it.

    Study Notes

    pH of a Solution

    • The pH of a solution with a hydrogen ion concentration of 10^(-8) mol/L is 8.

    Acid Types

    • A strong acid is an acid that completely dissociates in water, producing a high concentration of hydrogen ions.

    Buffer Solutions

    • A buffer is a solution that resists changes in pH when an acid or base is added to it.

    Acid Characteristics

    • Volatile acids, such as carbonic acid and hydrochloric acid, can be 'breathed off' as gases.

    Blood pH

    • The normal range for blood pH is between 7.35 and 7.45.
