Dissociation vs. Ionization: What's the Difference in Acids and Bases?

In summary, there is no clear distinction between dissociation and ionization when discussing acids and bases in the Arrhenius theory. While some sources may suggest a difference, they are often used interchangeably and neither has a distinct meaning in this context. It may make more sense to speak about ionization for substances like NH3, but there is no strict rule for using these terms.

Why we always say that acid dissociates in water while bases ionizes in water
knowing that both gives ions?
What is the difference between dissociation and ionization in this field?

One site is not a proof that "we ALWAYS say" something.

As far as I am aware in this context "dissociation" and "ionization" are often used interchangeably, and neither has a distinct meaning.

To some extent it makes a bit more sense to speak about ionization of NH3 than about dissociation, as it reacts with water producing ion but doesn't dissociate per se (as opposed to the acetic acid for example). But there is no rigor in using these terms.
 

Related to Dissociation vs. Ionization: What's the Difference in Acids and Bases?

1. What is the difference between dissociation and ionization?

Dissociation is the separation of a compound into ions, while ionization is the process of converting a neutral atom or molecule into an ion by adding or removing electrons.

2. How does dissociation and ionization occur?

Dissociation can occur through various processes such as electrolysis, heat, or chemical reactions. Ionization can occur through exposure to high-energy radiation or through collisions with other particles.

3. What is the role of dissociation and ionization in chemical reactions?

Dissociation and ionization play important roles in chemical reactions by allowing for the formation of new compounds and the transfer of electrons between atoms.

4. How are dissociation and ionization measured?

Dissociation can be measured through changes in physical properties such as conductivity or pH. Ionization can be measured through spectrometry or by detecting the presence of ions.

5. Can dissociation and ionization occur in nonpolar substances?

No, dissociation and ionization typically occur in polar substances where there is a separation of charge. Nonpolar substances do not have this separation of charge and therefore do not undergo dissociation or ionization.
