acid and bases definitions Flashcards
(17 cards)
acid (Arrhenius)
an acid is a substance that dissociates in water to form H+ ions
base (Arrhenius)
a base is a substance that dissociates to form OH- ions
strong acid (Arrhenius)
a strong acid a substance that fully dissociates in water to form H+ ions
strong base (Arrhenius)
a strong base is a substance that fully dissociates in water to form OH- ions
weak acid (Arrhenius)
a weak acid is a substance that partially dissociates in water to form H+ ions
weak acid (Arrhenius)
a weak acid is a substance that partially dissociates in water to form OH- ions
acid (Bronsted Lowry)
an acid is a proton donor
base (Bronsted Lowry)
a base is a proton acceptor
strong acid (Bronsted Lowry)
a strong acid is a good proton donor
strong base (Bronsted Lowry)
a strong base is a good proton acceptor
weak acid (Bronsted Lowry)
a weak acid is poor proton donor
weak base (Bronsted Lowry)
a weak base is a poor proton acceptor
conjugate acid
a conjugate acid is a base that gained a proton
conjugate base
a conjugate base is an acid that lost a proton
conjugate acid/base pair
a conjugate acid/base pair is any pair consisting of an acid and a base which differ by a proton
neutralisation
neutralisation is a reaction between an acid and a base to form salt and water
pH
pH= -log10 [H+] where the [ ] indicate the concentration of H+ ions in mol/L
