"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"?
