Acidic and basic solutions
Ions in acidic and basic
All aqueous solutions (as well
as pure water) contain hydroxide ions (formula OH-) and hydrogen ions
These ions are produced naturally by a chemical process that takes
place between water molecules.
When a solution is neutral there
are as many hydroxide ions as hydrogen ions.
Hydrogen ions are responsible for the acidity of a solution: when a
solution contains more hydrogen ions than hydroxide ions then the
solution is acidic.
hydroxide ions are responsible for the basicity of a solution: when
they outnumber the hydrogen ions then the solution is basic.
presence of hydroxide ions and hydrogen ions in pure water explains why
it is never totally insulative
