Acid Base Quiz
What is an Acid?
Acids in solution have a pH below 7.0, a sour taste, releases hydroxyl ions in water, and turn litmus paper red.
Arrhenius defined an acid is any substance that produces
H+ ions or H3O+ ions in water.
H+ ions are called hydrogen ions,
H3O+ ions are called hydroxonium ions.
What is a Base?
A substance that will neutralise an acid,
but does not dissolve in water, is called a base.
For example,
copper(II) oxide, iron(II) oxide and zinc carbonate are bases,
they do not dissolve in water
