What are chemical properties?
1. In addition to physical properties, substances have
chemical properties
that describe how a substance reacts
with other substances.
2. How easily one substance reacts with another substance
is called
reactivity
. For example, sodium is a
water
substance that reacts strongly with
.
3. The ability to catch on fire or burn is called
flammability
. Hydrogen, methane, and paper are
flammable
; they easily catch on fire.

18. A solution has a pH of 5. How will the solution taste? What
would it react with to form a salt?
The solution is acidic, so it would taste sour and would react with a
base to form a salt.
