Discussion Overview

The discussion revolves around the question of why 1 M NaOH does not spontaneously reduce hydronium ions. It explores concepts related to redox reactions, specifically focusing on the conditions under which reduction occurs and the nature of sodium in different chemical states.

Discussion Character

  • Homework-related, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant states that 1 M NaOH does not spontaneously reduce hydronium ions, despite sodium being a strong reducer.
  • Another participant questions the initial post by asking for clarification on "the following" substances that were not listed, implying that context is missing.
  • A participant draws an analogy comparing sodium and calcium, suggesting that being a strong reducer does not guarantee spontaneous reduction in all contexts.
  • One participant expresses confusion about the topic and requests an explanation regarding the redox process.
  • Another participant highlights the distinction between metallic sodium (Na) and oxidized sodium (Na+) in a compound, implying that this difference is crucial to understanding the reduction process.
  • A later reply acknowledges that oxidized sodium (Na+) is not a good reducer, suggesting a shift in understanding regarding the chemical behavior of sodium in different states.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the reasons behind the lack of spontaneous reduction of hydronium by NaOH. Multiple viewpoints are presented, and confusion remains regarding the underlying principles of redox reactions.

Contextual Notes

The discussion lacks clarity on the specific conditions or definitions that govern spontaneous reduction, and there are unresolved questions about the nature of sodium in its various forms.

Homework Statement



Which of the following does not spontaneously reduce 1 M hydronium ion?

Homework Equations



Spontaneous reduction: + E-zero value.

The Attempt at a Solution



The answer is 1 M NaOH. However, sodium is a very strong reducer. Why doesn't this reaction go spontaneously?

And what are "the following", which you have not listed?

While sodium is a strong reducer, kitchen salt doesn't reduce my meals. Calcium is a strong reducer too, but despite being present in my bones, it doesn't reduce me to... something reduced. Can you think why?
 
I really have no clue. I've been looking at redox for the past twelve hours. An explanation would b highly appreciated!
 
But you do know the difference between metallic sodium (Na) and oxidized sodium (Na+) in a compound?
