"acid rain" is generally considered to be rain that has a pH below
hydroxide ions (OH-)
a base dissolved in water generates
less than OH-
a basic solution is one in which the hydronium ion concentration is
sour
a food that contains acids likely tastes
loses a hydrogen ion
a hydroxide ion results when a water molecule
has a great tendency to gain them
if a strong acid has a great tendency to lose hydrogen ions, than a strong base
has a small tendency to gain them
ifa weak acid has a small tendency to lose hydrogen ions, then a weak base
10-3
the concentration of hydronium ions, H3O+, in a solution of pH=3 is
gains a hydrogen ion
the hydronium ion results when a water molecules
salt
the reaction of an acid and a base always results in the formation of
donate hydrogen ions
the stronger the acid, the greater its ability to
produces a large concentration of hydronium ions
to say that an acid is strong in aqueous solutions means the acid
hydronium ions, H3O+
we measure the "acidity" of a solution by measuring the concentration of
to concentration of hyrdonium ions equals the concentration of hydroxide ions, HO-
what does it mean to say one has a "neutral solution"?
