  • What does it mean for a substance to be a strong electrolyte?
    A strong electrolyte completely ionizes into its constituent ions in solution.
  • How do strong acids and bases behave in water?
    They dissociate completely, breaking up 100% into their ions.
  • What is indicated by a single arrow in the chemical equation for strong acids and bases?
    A single arrow shows that the reaction goes to completion and the product side is highly favored.
  • Why don’t you need an ICE chart for strong acids and bases when calculating pH or pOH?
    Because they dissociate completely, so their ion concentrations are equal to their initial concentrations.
  • How do you calculate the pH of a strong acid?
    Take the negative logarithm of the acid’s concentration.
  • How do you calculate the pOH of a strong base?
    Take the negative logarithm of the base’s concentration.
  • What is an example of a strong binary acid?
    HCl is a strong binary acid.
  • What is an example of a strong base with a Group 1A ion?
    NaOH is a strong base because it contains Na+ (a Group 1A ion) and OH-.
  • What does 'highly electrolytic' mean in the context of acids and bases?
    It means the acid or base breaks up completely into ions in solution.
  • What is the relationship between pH and pOH for strong acids and bases?
    Both are calculated using the negative logarithm of their respective ion concentrations.
  • What happens to HCl when it is dissolved in water?
    HCl dissociates completely into H+ and Cl- ions.
  • What happens to NaOH when it is dissolved in water?
    NaOH dissociates completely into Na+ and OH- ions.
  • Why is the product side highly favored in reactions involving strong acids and bases?
    Because the reactants dissociate completely, leaving mostly products (ions) in solution.
  • What does the term '100% ionization' mean for strong acids and bases?
    It means all of the acid or base molecules break up into ions in solution.
  • What is the key difference between strong and weak acids or bases regarding ionization?
    Strong acids and bases ionize completely, while weak acids and bases only partially ionize.
