Are atomic conductivity and standard reduction potential correlated?

Click For Summary

Discussion Overview

The discussion revolves around the relationship between atomic conductivity and standard reduction potential, exploring whether these two properties are correlated. The scope includes theoretical considerations and practical implications related to electrical conductivity in metals and solutions.

Discussion Character

  • Debate/contested, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant questions whether standard reduction potential can be represented in the equation V=IR, suggesting that V might correspond to standard reduction potential and R to the inverse electrical conduciveness of a metal.
  • The same participant notes an observed strong inverse correlation between reduction potentials and resistance in their plotted data.
  • The participant expresses confusion regarding the amperage required to calculate conductivity and discusses the relationship between conductivity, resistance, and cell constants.
  • Another participant challenges the initial claims by questioning the term "atomic conductivity" and pointing out the mix-up between the conductivity of metals and the conductivity of solutions, asking for clarification and a correlation plot.
  • This second participant also critiques the relevance of the referenced paper, stating it does not pertain to electrode potentials.

Areas of Agreement / Disagreement

Participants do not appear to agree on the definitions and relationships discussed, with one participant expressing confusion and the other challenging the initial claims. The discussion remains unresolved regarding the correlation between atomic conductivity and standard reduction potential.

Contextual Notes

There are limitations in the clarity of terms used, such as "atomic conductivity," and the relationship between different types of conductivity (metals vs. solutions) is not fully explored. The discussion also lacks specific data or plots to support claims made.

TL;DR
conductivity and standard reduction potential correlated?
I have no idea whether in V=IR, V can be standard reduction potential, and R is inverse electrical conduciveness of that metal.
I plotted the reduction potentials and they are strongly inversely correlated with resistance.

I'm more confused by this because I have no idea how much amperes "A" we shock a metal to calculate its conductivity.

"We can find how conductive the cell is by multiplying conductivity by the cell constant. The cell constant magnitude helps determine how conductive a cell is. Solution resistance is the opposite of conductivity, so if a solution has a high resistance value, it will not be very conductive, and thus the cell containing this solution will also be a poor conductor. And if a solution has high conductivity, it will have a low resistance.

So we can also find the conductivity by dividing the cell constant by resistance

Conductivity = (cell constant 1/A) / (resistance)"

I looked at pchem notes but I'm more confused by those.https://web.mnstate.edu/marasing/CHEM450/LABLS/450 Labs/Conductance of Solutions/Conductimetric Determination of Ka of Weak Acids.pdf

What are you talking about here? What is "atomic conductivity"? You talk about conductivity of metals, then conductivity of cells (which is determined by solution properties). Can you show the correlation plot you mention? The paper you reference has nothing to do with electrode potentials.
