identify wether a
substance is an acid or
a base
It indicates acid or base
by changing color or
displaying a digital
reading
15. A symbol used to
represent the percent
of the Hydrogen Ion
(Acid Level) in a
substance.
▪Ranges from 1 (Acid)
– 15 (Base)
16. ▪ One tool used with indicators that is
used to indicate the strength of an
acid or a base.
17. ▪ A value of 1 indicates a strong acid
▪ Battery Acid (Sulfuric Acid; H2S O4)
▪ A value of 7 represents a neutral
(our blood and saliva are a pH of 7)
▪ A value of 15 represents a strong
base
▪ Oven Cleaner, Draino, Ammonia, Soap

27. Acids and Bases are all around us
Bases can be strong or weak having a
pH value ranges between 8 – 15, 8
being the weakest and 15 the
strongest
28. Strong bases can burn you; weak
Bases wont
A value of 8 – 9 is weak
Hand soap, Detergent, Ammonia
A value of 13 - 15 is strong.
Oven Cleaner, Drain Cleaner
29. Something that is “Neutral” has a
pH of 7. (Our bodies are neutral.)
When an acid and a base are
combined a process called
“Neutralization” occurs.
30. During neutralization the reactants
(acid + base) combine to form two
products..
Water H2O
A compound called a “Salt”
