  • What are the two main types of acids discussed in the context of Arrhenius acids and bases?
    The two main types are binary acids and oxy acids.
  • According to Arrhenius, what ion must a compound produce in water to be classified as an acid?
    It must produce H+ (hydrogen ion) in water.
  • What is the fundamental ion produced by an Arrhenius base in aqueous solution?
    An Arrhenius base produces OH- (hydroxide ion) in water.
  • What is the main limitation of the Arrhenius definition of acids and bases?
    It only applies to aqueous (water-based) environments and does not describe behavior outside of water.
  • What happens when HCl is dissolved in water according to the Arrhenius definition?
    HCl dissociates to form H+ and Cl- ions in water.
  • What is an example of an Arrhenius base and what does it produce in water?
    NaOH is an example; it produces Na+ and OH- ions in water.
  • Why does the Arrhenius definition not consider compounds without H+ as acids?
    Because it requires the presence of H+ to classify a compound as an acid.
  • Does the Arrhenius definition apply to both strong and weak acids? Why or why not?
    Yes, because any compound that produces H+ in water is considered an Arrhenius acid.
  • What must a compound produce to be classified as an Arrhenius base?
    It must produce OH- ions when dissolved in water.
  • What is the broadest and earliest definition of acids and bases among the three main definitions?
    The Arrhenius definition is the broadest and earliest.
  • What is the key requirement for a compound to be an Arrhenius acid or base?
    It must contain H+ (for acids) or OH- (for bases) and release them in water.
  • What is the solvent required for the Arrhenius definition to apply?
    The solvent must be water (aqueous solution).
  • If a compound does not produce H+ or OH- in water, how is it classified under the Arrhenius definition?
    It is classified as neither an Arrhenius acid nor an Arrhenius base.
  • Why is the Arrhenius definition considered less precise than later definitions?
    Because it is very broad and only considers the presence of H+ or OH- in water.
  • What should you do to determine if a compound is an Arrhenius acid, base, or neither?
    Dissolve it in water, observe the ions produced, and check for H+ (acid) or OH- (base).
