Acids and Bases vocabulary

Match the word to its meaning for the unit on acids and bases (chemistry).

AB
acidproduces hydrogen ions when dissolved in water
HFhydrofluoric acid
H2SO4sulfuric acid
HNO3nitric acid
Almost always starts with "H"acid
basea compound that produces hydroxide ions when dissolved in water
OH-hydroxide ion
H+hydrogen ion, used the same way as H3O+
H3O+hydronium ion, used the same way as H+
self-ionizationthe reaction in which two water molecules react to give ions (H+ and OH-)
Kwthe ion product constant for water
acidic solutionone where the H+ concentration is greater than the OH- concentration
basic solutionone where the H+ concentration is less than the OH- concentration
1 x 10 -6 mol/Lan acidic solution
1 x 10 -8 mol/La basic solution
pH of a solutionthe negative log of the [H+]
pOH of a solutionthe negative log of the [OH-]
monoprotic acidone H+ (proton) can be ionized (removed) from the compound
diprotic acidtwo H+ (protons) can be ionized (removed) from the compound
triprotic acidthree H+ (protons) can be ionized (removed) from the compound
H3PO4an acid which could be triprotic
H2CO3an acid which could be diprotic
Bronsted-Lowry acida hydrogen ion donor
Bronsted-Lowry basea hydrogen ion acceptor
conjugate acidan acid formed when a base accepts (gains) an H+
conjugate basea base formed when an acid donates (gives away) an H+
amphoterica substance that can act as both an acid and a base (such as H2O)
Arrhenius acidcompound containing hydrogen that can ionize to produce H+
Arrhenius basecompound containing hydroxide that can ionize to produce OH-
Kaacid dissociation constant: the ratio of [dissociated acid]/[undissociated acid]
Kbbase dissociation constant: the ratio of [dissociated base]/[undissociated base]
dissociatedionized: taken apart
concentratedlarge number of acid or base moles in solution: high M
dilutesmall number of acid or base moles in solution: low M
strong acid or baseone that dissociates (ionizes) completely in solution
weak acid or baseone that only dissociates (ionizes) a small amount in solution
indicatora weak acid or base that will ionize at a certain pH range producing color changes
