Acids and bases
- Arrhenius
- Theory
- Acids are the substances which they produce the hydrogen ions in a solution.
- Bases are substances in which they produce hydroxide
ions in the solution.
- Bases are substances in which they produce hydroxide
ions in the solution.
- Acids are the substances which they produce the hydrogen ions in a solution.
- An Arrhenius acid is a
substance that when added
to water increases the
concentration of H1+ ions
present. The chemical
formulas of Arrhenius acids
are written with the acidic
hydrogens first. An
Arrhenius base is a
substance that when added
to water increases the
concentration of OH1- ions
present. HCl is an example
of an Arrhenius acid and
NaOH is an example of an
Arrhenius base.
- Theory
- Bronsted-Lowry
- Theory
- An acid is a proton (hydrogen ion) donor.
- A base is a proton (hydrogen ion) acceptor.
- A base is a proton (hydrogen ion) acceptor.
- An acid is a proton (hydrogen ion) donor.
- Bronsted-Lowry acid is
defined as anything
that releases H1+ ions;
a Bronsted-Lowry base
is defined as anything
that accepts H1+ ions.
This definition includes
all Arrhenius acids and
bases but, as we will
soon see, it is a bit
more general
- Theory
- Lewis
- Theory
- A Lewis acid is an electron pair acceptor.
- A Lewis base is an electron pair donor.
- A Lewis base is an electron pair donor.
- A Lewis acid is an electron pair acceptor.
- Lewis theory suggests that acids react
with bases to share a pair of electrons,
with no change in the oxidation
numbers of any atoms. Many chemical
reactions can be sorted into one or the
other of these classes. Either electrons
are transferred from one atom to
another, or the atoms come together to
share a pair of electrons.
