Acids, Bases & Salts Flashcards
Arrhenius Acid
Substance that yields hydrogen ions in an aqueous solution
Arrhenius Base
A substance that yields hydroxide ions in an aqueous solution
Bronsted-Lowry Acid
Proton donors
Bronsted-Lowry Base
Proton acceptors
Conjugate Base
Original acid donates a proton
Remaining ion is capable of accepting a proton (base)
Conjugate Acid
Original base accepts a proton
Remaining ion is capable of donating a proton (acid)
Lewis Acid
Electron-pair acceptor
Lewis Base
An electron-pair donor
Buffer Solutions
Equilibrium systems that resist changes in acidity & maintain constant pH when acids/bases are added to them
Salt
Ionic compound containing positive ions other than hydrogen ions & negative ions other than hydroxide ions
Amphoteric
Molecules that can act as either acids (H donors) or bases (H acceptors)
Acid Rain
Forms when the oxides of sulfur & nitrogen combine with atmospheric moisture to yield sulfuric & nitric acids (very corrosive)
