2. An acid is a chemical substance
whose aqueous solutions are
characterized by a sour taste,
the ability to turn blue litmus
red, and the ability to react
with bases and certain metals
(like calcium) to form salts.
Aqueous solutions of acids have
a pH of less than 7.
3. pH less than 7
Neutralizes bases
Forms H
+
ions in solution
Corrosive-reacts with most
metals to form hydrogen
gas
Good conductors of
electricity
6. Acid rain is a rain or any
other form of precipitation
that is unusually acidic,
meaning that it possesses
elevated levels of hydrogen
ions (low pH). It can have
harmful effects on plants,
aquatic animals and
infrastructure.
