a conjugate acid-base pair
what is two species, one an acid and one a base, that differ from each other though the loss or gain of a proton?
one more H atom and one fewer negative charge
the acid in the acid-base pair always has how many H atoms and how much negative charge as opposed to the base?
a conjugate acid
what is the species formed when a proton (H+ ion) is added to a Bronsted Lowry base?
a conjugate base
what is the species formed when a proton (H+ ion) is removed from a Bronsted Lowry acid?
an amphiprotic substance
what is a substance that can either lose or accpet a proton and thus can function as either a Bronsted-Lowry acid or a Bronsted-Lowry base?
a monoprotic acid
what is an acid that supplies one proton per molecule during an acid-base reaction
