Talk:Conductivity (electrolytic)

A fact from Conductivity (electrolytic) appeared on Wikipedia's Main Page in the Did you know column on 19 May 2009 (check views). The text of the entry was as follows:

Did you know... that while the electrical conductivity of pure water is very low, the conductivity of drinking water can be thousands of times greater?

A record of the entry may be seen at Wikipedia:Recent additions/2009/May.

If power plant water chemistry, it is common to compare AC and DC - but no mention of it here. Would an expert care to provide the details, or should I have a go? (Careful - I am only a mechanical engineer!)--Graham Proud (talk) 02:30, 16 February 2013 (UTC)[reply]

Conductivity minimum interpretation alternatives[edit]

What are the alternatives to ion association in explaining the minimum?--188.26.22.131 (talk) 09:38, 19 August 2013 (UTC) The conductivity is measuring water. — Preceding unsigned comment added by 217.164.238.237 (talk) 19:29, 22 May 2014 (UTC)[reply]

Connection to normal concentration[edit]

The connection between electrotytic conductivity and the normal concentration, although not explicitly detailed in the articles, is that that electrolytic conductivity has two expressions: molar and equivalent and the normal concentration (of a ionic solution which has electrolytic conductivity) is the equivalent concentration of ions.--5.15.207.48 (talk) 14:53, 19 October 2013 (UTC)[reply]

Isotopic effect[edit]

Are there some data available concerning numerical value differences of conductivity due to isotopic effects in heavy water (lithium) ionic solutions compared to light water? A source by an author (Gary Taubes), used in cold fusion article, makes reference to such a difference but it seems to not mention some numerical values.--188.27.144.144 (talk) 10:10, 25 June 2014 (UTC)[reply]

Frequency of the current[edit]

The article mentions that the conductivity is measured at frequency of current of 1-3 kHz. Is this frequency enough to eliminate the possibility of electrolysis?--188.26.22.131 (talk) 15:57, 27 June 2014 (UTC)[reply]

Link between conductivity and thermodynamic activity coefficient[edit]

The article should specify the connection between conductivity and the thermodynamic activity coeffient.--188.26.22.131 (talk) 12:55, 9 September 2014 (UTC)[reply]

I've noticed a journal article re the proposed addition to this article in The Journal of Chemical Physics : https://doi.org/10.1063/1.1698801 .--178.138.192.180 (talk) 20:11, 26 October 2021 (UTC)[reply]

Definitions[edit]

The definitions of C and G* are not clear. C appears to be defined as l/A and later the section says, "Sometimes the ratio of l and A is called as the cell constant, denoted as G*" without indicating how the ratio is formed. On examining the usages of the two terms, C and G*, it would seem the two are reciprocals of one another. It would be useful to specify this clearly, C = l/A and G* = A/l.--Gnuarm (talk) 07:02, 7 March 2015 (UTC)[reply]

Lambda factor and the law of dilution[edit]

I have encountered in some NON-Eng electrochemistry texts a mention of a Lambda factor f_λ in the expression of conductivity, namely the ratio of conductivity and limiting conductivity Λ⁰. This mentioned quantity is mentioned presumably in ENG electrochemistry sources like Double layer and electrode kinetics by Paul Delahay, ratio expressed as product of the Ostwaldian dissociation degree in the law of dilution and the previously mentioned f_λ

I think a section re the conductivity in mixed solvents, for instance water alcohols, could be added to the article.--213.233.84.222 (talk) 18:53, 26 July 2018 (UTC)[reply]

Units[edit]

I do not understand the explanation of units. The article states, "The commonly used standard cell has a width of 1 cm". This is seems to be an incomplete and inadequate explanation of the units. What is this cell? What does it look like? Is it a pair of plates immersed in the water to be tested or something else? What part of the cell is this "width" describing? What is the standard distance between the plates? What is the size of the plates? Are they square, rectangular, round, triangular, a single point or what? All of these things may affect the current through the water. Please describe a standard cell and what the "cm" refers to. 24.138.44.20 (talk) 19:38, 26 May 2019 (UTC)[reply]
