Substances that
tastes sour
Acids
(lemons, limes, oranges)
Substance that is slippery
Bases
(soap is a weak base)
Substance that tastes Bitter
Base
Substance that emulsifies
fats and oils.
Base
For example, soap breaks
apart fats and oils to make
you’re your dishes clean.
Substance that dissolves in
water to produces positive
hydrogen (H+) ions
Acids break
apart in water
to produce H+
ions.
Substance that dissolves in
water to produces hydroxide
(OH-) ions.
Bases produce OH- ions.
OH- combines with a H+
from acids to form water
When you combine an
acid and a base, what
do you form?
2 neutral substances.
Water and a salt
What type of reaction is a
neutralization reaction?
Double replacement reaction.
Finish the reaction.
2HBr + Ba(OH)2
____2 + 2___
Neutralization reaction
2HBr + Ba(OH)2
BaBr2 + 2H2O
a type of salt
water
a) What is heartburn?
b) What can you do to
relieve the discomfort?
a) Stomach acids that enter the
esophagus and eat away at
the tissue which causes
discomfort.
b) An antacid will neutralize
the stomach acid and relieve
the discomfort.
a) Acids always start with
what?
b) Bases usually end with
what?
a)
Acids start with H.
For example: HCl and H2SO4
Hydrochloric and sulfuric acid
b) Bases usually end with OH
For example NaOH and KOH
What causes acid rain?
Cars burn gasoline to produce NO2
Factories and power plants burn
coal to produce SO2
Write down the Jeopardy question and
answer.
Hand in before the test for extra credit.
What are 2 things
you can do to
prevent acid rain?
Walk more and ride your bike
instead of having your parents give
you a ride. Carpool or take a bus.
(etc)
Use less energy. Turn off the lights
when leaving a room or turn off
your computer at night. (etc)
What are 2 ways companies
are reducing the amount of
acid rain?
Smoke stack scrubbers: Spray CaO
and water on the smoke, which
reacts with the SO2 to prevent it
from entering the atmosphere.
Catalytic converters are in the exhaust
system in cars. They turn
harmful chemicals into less
harmful ones.
If there is a lake that is
acidic, what can we do to
make it livable for aquatic
organisms. Why?
Spraying a base such as calcium
carbonate (chalk) will
neutralize the acid,
creating salt and water, to
make it livable for aquatic
organisms.
Make your wager
What is the difference between
a strong acid and a weak acid?
This is not the EC question
Strong acids break apart completely
when put into water while weak acid
only partially break apart.
Good luck on the Chemistry test!
