Common Acids and Bases:
Directions: Complete these paragraphs by
filling in or circling the appropriate information based on the
information that you know about acids and bases. You may have to use
Google to find the answers.
When most people think of chemistry the first terms that come to mind
are acids and bases. Many of the chemicals that people run across have
some connection to acids and bases. For instance many
people take medicine every day to cure heartburn. These
medicines are (acids/bases). One of these comes in a blue
bottle and is known as “Dr. MOM”. The common name for
this is Milk Of Magnesia the IUPAC name for this substance is
__________________________ and the chemical
formula is _________________. Another product
claims that it is better for us to use because it contains
calcium. So in addition to helping relieve the heartburn, it
also provides us with needed calcium. This product is called
Tums and its IUPAC chemical name is ________________
and its chemical formula is _________________.
Another product that is used all the time is Drano.
Drano is a(n) (acid/base) and it has the common name
of “lye” the IUPAC chemical name is
_____________________________, and the chemical
formula is ___________________. This chemical is more
dangerous than the ones used for heartburn and can
cause blindness or burns. (Acids/Bases) are also commonly used to
produce soaps and have a (bitter/sour) taste.
Seltzer water and all sodas contain a very mild (acid/base) know as
_____________________. Dissolving carbon dioxide in water forms this
substance. The chemical formula for this substance is ______________.
Vinegar is a(n) (acid/base) finds its way into our diet in ketchup and
most salad dressings. The chemical name for vinegar is
_____________________, the chemical formula for this substance is
_______________________.

An ____________ is a compound that contains hydrogen and releases
__________ (H+) in water. Acids often taste _______________ and
many acids can ________________ you if you touch them. Another
property of acids is that they react with _____________ to produce
hydrogen gas as acid dissolves the metal material.
There are many different kinds of acids. Lemon juice and
_____________ are examples of acids. There is even a very strong acid
in your stomach called ____________________acid. This acid helps you
________________food. You can use blue____________ paper to
determine is something is an acid or not because the acid will turn the
paper red.
Bases on the other hand are compounds that contain a metal and a
polyatomic ion called __________________ion. Bases dissolve in water
and dissociate (separate) into ions. Bases feel _______________ when
you touch them and taste ______________.
Many
household
cleaners are
bases. Some
bases can
even
dissolve hair
and food,
which makes
them ideal
for clearing,
clogged
drains.

Acids and Bases
How do acids and bases behave in water?
Acids and bases play an important role in our lives. Numerous
biological processes, industrial applications, and even environmental
problems are a function of the acidity or basicity (alkalinity) of
aqueous solutions. It is therefore important to understand what makes
a substance behave as an acid or a base when dissolved in water. In
this activity, we will explore the physical and chemical properties of
acids and bases.
