Review for Acids and Bases Vocabulary Test
Question | Answer |
---|---|
a chemical dye whose color is affected by acidic and basic solutions | acid-base indicator |
the value of the equilibrium constant expression for the ionization of a weak acid | acid ionization constant |
a solution that contains more hydrogen ions than hydroxide ions | acidic solution |
describes water and other substances that can act as both acids and bases | amphoteric |
states that an acid is a substance that contains hydrogen and ionizes to produce hydrogen ions in aqueous solutions and a base is a substance that contains a hydroxide group and dissociates to produce hydroxide ions in an aqueous solution | Arrhenius model |
the value of the equilibrium constant expression for the ionzation of a base | base ionization constant |
a solution that contains more hydroxide ions than hydrogen ions | basic solution |
states an acid is a hydrogen ion donor and a base is a hydrogen ion acceptor | Bronsted-Lowery model |
a solution that resists changes in pH when limited amounts of acid and base are added | buffer |
the amount of acid or base a buffer solution can absorb without a significant change in pH | buffer capacity |
the species produced when a base accepts a hydrogen ion from and acid | conjugate acid |
consists of 2 substances related to each other by the donating and accepting of a single hydrogen ion | conjugate acid-base pair |
the species produced when an acid donates a hydrogen ion to a base | conjugate base |
the point at which an indicator used in a titration changes color | end point |
the stoichiometric point of a titration | equivalence point |
a reaction in which an acid and base react to produce a salt and water | neutralization reaction |
the negative logarithm of the hydrogen ion concentration of a solution | pH |
the negative logarithm of the hydroxide ion concentration of a solution | pOH |
an ionic compound made up a the cation from a base and the anion from an acid | salt |
the process in which the anions from a dissociated salt accepts the hydrogen ions from water or the cations of the dissociated salt donates hydrogen ions to water | salt hydrolysis |
an acid that ionizes completely in an aqueous solution | strong acid |
a base that dissociates entirely into metal ions and hydroxide ions in an aqueous solution | strong base |
the process in which an acid-base neutralization is used to determine the concentration of a solution of unknown concentration | titration |
acid that ionizes only partially in dilute aqueous solutions | weak acid |
base that ionizes only partially in dilute aqueous solution to form a conjugate acid of the base and hydroxide ions | weak base |
