Acidic and Basic Solutions
CHAPTER 8, SECTION 3
When dissolved in water, these substances
RELEASEhydrogen ions (H+)
which bond with the water (H2O) to
producehydronium ions (H3O-)
ACID
When dissolved in water, these substances
ACCEPThydrogen ions (H+) from water which
produceshydroxide ions (OH-)

Touch Not Slippery Slippery
ACID/BASE Comparision
Measure of how acidic or basic a
solution is, ranging in a scale from 0 to 14; also refers to the ‘potential of
Hydrogen’
pH
A pH of 0-6.9 is
considered…
ACIDIC(pH of 0 is strongest)
A pH of 7.1-14 is considered…
BASIC(pH of 14 is strongest)
A pH of 7 is considered…

Compound that changes color at
different pH values when it reacts with
acidic or basic solutions
INDICATOR
Interaction that occurs between acids
and bases in which the properties of each are canceled out by the other
NEUTRALIZATION
H3O-
* Produced when acids release/give up H+ ions to
water
•Acid + H2O → Acid + H3O-
HYDRONIUM ION
OH-
* Produced when bases accept/gain H+ ions from
water
•Base + H2O → Base + OH-
HYDROXIDE ION
