Effect of thermal motions on cations

edit

The flow of cations in an electric field cannot be due to random thermal motions. It is due to the electric field, and opposed by random thermal motions. — Preceding unsigned comment added by 82.1.212.98 (talk) 06:44, 14 September 2018 (UTC)Reply

Yes, you are right. I have now corrected the article. Dirac66 (talk) 02:21, 27 September 2018 (UTC)Reply

@Rod57 Thank you. I have now added a mention at the end of the article. Dirac66 (talk) 03:49, 13 November 2022 (UTC)Reply

Incorrect formula for water?

edit

The article says:

In his 1806 publication “Theory of decomposition of liquids by electrical currents”, Theodor Grotthuss proposed a theory of water conductivity.[1] Grotthuss envisioned the electrolytic reaction as a sort of ‘bucket line’ where each oxygen atom simultaneously passes and receives a single hydrogen ion. It was an astonishing theory to propose at the time, since the water molecule was thought to be OH not H2O and the existence of ions was not fully understood.

Did most chemists really believe water was OH as late as 1806? John Baez (talk) 08:56, 9 June 2024 (UTC)Reply

The modern chemical formulae of simple molecules such as H2O and CH4 were only introduced in the 1850s by Frankland and Kekulé. See Valence (chemistry)#Historical development. Dirac66 (talk) 12:45, 9 June 2024 (UTC)Reply
