What Is a Acid?
An acid is a substance witch reacts with an Alkali
(base.) On the PH scale an acid is under seven. If
you mix a acids with a alkali it is called
neutralisation. There are many types of acids and
alkalis, here are some of the dilute ones
hydrochloric acid, sulfuric acid and nitric acid. It is
a non-metal substance. A Bee sting is acidic and

chemical burn (caustic.) Also alkalis
neutralize acids. And a Wasp sting is
alkaline and so its effects can be
