Discussion Overview

The discussion revolves around the pH of solutions containing the compounds (CH3)3NH+Cl- and (CH3)4N+Cl-. Participants are exploring whether these solutions are acidic, basic, or neutral when dissolved in water.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant suggests that (CH3)3N+Cl- is acidic and (CH3)4N+Cl- is neutral.
  • Another participant challenges the first claim about (CH3)3N+Cl-, stating that there is an anion (Cl-) but no cationic component, implying a misunderstanding.
  • A later reply corrects the formula to (CH3)3NH+Cl-, indicating that it should be considered slightly acidic due to being a protonated weak base.
  • There is a reference to a previous discussion on the topic, suggesting that this is not the first time the question has been raised.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the pH characteristics of the solutions, with some asserting different properties for (CH3)3NH+Cl- and (CH3)4N+Cl-.

Contextual Notes

There is a noted typo in the chemical formula for (CH3)3NH+Cl-, which may affect the interpretation of its acidity. The discussion also references a prior conversation, indicating that the topic may have complexities not fully resolved in this thread.

Acidic, Basic, or nuetral?

If each was dissolved in water, will the solution be acidic, basic, or neutral?

1) (CH3)3N+Cl- Acidic
2) (CH3)4N+Cl- Nuetral

Are these right?

Thanks

Sorry, I couldn't find it and could not remember what we had decided. Thanks

On the other I had a typo. It should be

(CH3)3NH+Cl-
 
Okay, that one should be slightly acidic. A protonated weak base will be a weak acid.
