iwhat is d difference between dissociation and ionisation?

Question

only sensible answers plz.

Answer 1

Ionization:
Process by which electrically neutral atoms or molecules are converted to electrically charged atoms or molecules (ions) by the removal or addition of negatively charged electrons.

Dissociation:
Dissociation is a general process in which complexes, molecules, or salts separate or split into smaller molecules, ions, or radicals, usually in a reversible manner. Dissociation is the opposite of association and recombination.

Answer 2

From Wikipedia:

Dissociation in chemistry and biochemistry is a general process in which complexes, molecules, or salts separate or split into smaller molecules, ions, or radicals, usually in a reversible manner.

Ionization: The process of converting an atom or molecule into an ion by changing the difference between the number of protons and electrons.

My explanation: ionization ALWAYS refers to an atom's gain or loss of electron(s) to make a charged particle (an ion), while dissociation does not necessarily result in an ion. In biochemistry, dissociation usually means loss of one or more protons (H+) and is often used as a synonym to ionization.

Please remember that ions can also be polyatomic, ie. sulfuric acid (H2SO4) loses two H+ to make sulfate (SO4).
