Questions and Answers

What is the primary role that acids and bases play in relation to each other?

  • Acids release positively charged hydrogen ions and bases accept these ions (correct)
  • Acids and bases accept hydroxide ions
  • Acids accept negatively charged hydroxyl ions and bases release these ions
  • Acids and bases release negatively charged hydrogen ions

How did Arrhenius define acids and bases differently from the classical definition?

  • Acids release hydroxyl ions while bases accept protons
  • Acids release hydrogen ions while bases increase the concentration of hydroxyl ions
  • Acids increase the concentration of hydroxide ions while bases release protons
  • Acids release hydrogen ions upon dissociating while bases increase the concentration of hydroxyl ions (correct)

What happens when an acid-base reaction occurs?

  • Protons are accepted by the base from the acid
  • Only protons are exchanged between the acid and base
  • Protons and electrons are exchanged between the acid and base (correct)
  • Electrons are accepted by the acid from the base
