Nuetralization Reaction involving a weak acid and weak base

Click For Summary

Discussion Overview

The discussion revolves around the classification of a reaction between acetic acid (CH3OOH) and ammonia (NH3) as a neutralization reaction involving a weak acid and weak base. Participants explore the implications of different definitions of neutralization and compare this reaction to one involving acetic acid and sodium bicarbonate.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions whether the reaction between acetic acid and ammonia qualifies as a proper neutralization reaction, suggesting that a reaction with sodium bicarbonate might be more appropriate.
  • Another participant notes that the definition of "neutralization" could vary, indicating that if neutrality is defined as achieving a pH of 7, then the resulting ammonium acetate could meet that criterion.
  • It is mentioned that ammonia, being a gas, could lead to improper neutralization, which raises concerns about the reaction's effectiveness.
  • A participant argues that the salt formed from the reaction (NH4+) is a significant acid, implying that the resulting solution may not be neutral.
  • There is a suggestion that the reaction could be treated as a buffer solution, indicating a potential complexity in the behavior of the resulting mixture.

Areas of Agreement / Disagreement

Participants express differing views on whether the reaction qualifies as a neutralization reaction, with no consensus reached on the definitions or implications of the reactions discussed.

Contextual Notes

Participants highlight the dependence on definitions of neutralization and the implications of the resulting pH, as well as the potential for improper neutralization due to the gaseous nature of ammonia.

CH3OOH (aq) + NH3 (aq) ‹———› NH4+ (aq) + CH3COO- (aq)

Would the above reaction, involving acetic acid and ammonia qualify as a proper neurtalization reaction involving a weak acid and weak base? Or, would a reaction involving acetic acid and sodium bicarbonate be better?

It depends on what you understand from "neutralization". If you mean pH=7 point for it, then ammonium acetate will almost just give pH=7 level. If you mean equimolar acid/base pair, then the second one will fit better.

Ammonia is okay, but it is a gas and there is a probability of improper neutralization.

By the way, welcome to the forum.
 
Probably not. The salt formed through such a reaction will contribute to the pH, NH4 is a significant acid.
 
The above could be treated as a buffer solution, right?
