Discussion Overview

The discussion centers on the species present in an aqueous solution of CH3COONa, exploring the various ions and molecules that may exist in this context. Participants consider both the dissociation of the salt and the interactions with water.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant identifies CH3COO- and Na+ as present from the dissociation of CH3COONa.
  • It is suggested that CH3COONa remains in solution because the dissociation does not go to completion.
  • H3O+ and OH- are noted as present due to the autoionization of water.
  • A participant proposes that CH3COOH may form from a reaction between CH3COO- and H3O+.
  • Another participant introduces the idea of NaHO forming from a reaction between Na+ and OH-, which is challenged by a subsequent response.
  • A participant acknowledges the correction regarding the formation of NaOH.

Areas of Agreement / Disagreement

Participants generally agree on the presence of CH3COO-, Na+, H3O+, and OH-. However, there is disagreement regarding the formation of NaHO, which is contested.

Contextual Notes

The discussion does not resolve the implications of the presence of CH3COOH or the conditions under which NaHO might form, leaving some assumptions and dependencies on definitions unaddressed.

What species are present in aqueous solution CH3COONa (other than H20)?

My thoughts:
CH3COO- and Na+ are present from the reaction.
CH3COONa is present because the reaction does not go to completion.
H30+ and OH- are present from the autoionization of water.
CH3COOH is present from a reaction between CH3COO- and H3O+.

Do I have the right idea here or am I missing something? Thanks.

Yeah, I think you got them all.
 
And NaHO from the reaction between Na+ and HO- ?
 
NaOH is a strong base, so it will not form; he already covered the Na+ and OH- ions.
 
Ok, sorry, you are obviously right.
