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

Click For Summary

Discussion Overview

The discussion centers on the terminology used to describe the behavior of acids and bases in water, specifically the terms "dissociation" and "ionization." Participants explore the nuances of these terms within the context of acid-base theories, including the Arrhenius theory, and question the consistency of their usage.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant questions why acids are said to "dissociate" while bases "ionize," suggesting both processes produce ions.
  • Another participant expresses uncertainty about the distinction, noting they have not observed a difference in usage.
  • A third participant references the Arrhenius theory of acids and bases, implying that definitions may vary based on theoretical context.
  • One participant argues that "dissociation" and "ionization" are often used interchangeably, indicating a lack of distinct meaning in this context.
  • It is suggested that the term "ionization" may be more appropriate for substances like NH3, which reacts with water to produce ions without a clear dissociation process, contrasting with substances like acetic acid.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the distinction between dissociation and ionization, with multiple competing views expressed regarding their definitions and usage.

Contextual Notes

There is a lack of rigor in the definitions of "dissociation" and "ionization," and the discussion highlights the potential for ambiguity in their application to different substances.

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?

Why we always say

I have not noticed.
 
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.
