Talk:Daniell cell

Usually in all cells, the terminal undergoing oxidation is called the anode. Here, in a Daniel Cell, the Zinc terminal undergoes oxidation. And yet, it is the cathode. This is one speciality of a Daniel Cell.

:No, it's not. The Zinc terminal is the anode. 24.6.66.193 07:14, 20 April 2007 (UTC)

I have expanded this article by adding text from Wet cell. Biscuittin 11:59, 2 June 2007 (UTC)

Sulphates and sulfates - the more accepted these days is to use 'f'. In the article there is 'ph' as well as 'f'. Change? —Preceding unsigned comment added by Number 8 (talk • contribs) 08:38, 22 November 2007 (UTC)

I found it odd when reading this article that the section about a variant (about the gravity cell), came before the description of the cell's chemistry. Would it not be more logical to explain the basic cell first before describing variants? Additionally, would it be possible to have both the 'Gravity Cell' and 'Porous Pot Cell' headings to be grouped into a 'Variations' or 'Types' section, as it is not immediately apparent that that is in fact what they are.

14.97.59.78 (talk) 16:37, 13 July 2011 (UTC) what is the average emf of the daniel cell? plzz help. anyone. i am at earnest...

:This is now in the lede section of the article. SpinningSpark 10:14, 23 October 2013 (UTC)

I can see no justification for flagging 'Daniel' as a variant spelling - a search shows almost all authoritative sources as Daniell. The single 'l' is erroneous and shouldn't be encouraged as an alternative or variant.

can we find an illustration of a cell that is not labelled in french? — Preceding unsigned comment added by 64.78.84.210 (talk) 00:07, 23 October 2013 (UTC)

The two half-cell form of the Daniell cell for classroom demonstrationsZn(s) → Zn2+(aq) + 2e− . . (Standard electrode potential -0.7618 V )

At the cathode, copper is reduced per the following reaction:

Cu2+(aq) + 2e− → Cu(s) . . (Standard electrode potential +0.340 V )Please delete or correct the diagram! — Preceding unsigned comment added by 165.228.16.225 (talk) 11:44, 19 March 2018 (UTC)

The picture does not match the text in the Chemistry section. What ions are in the salt bridge? The text speaks of nitrate and potassium ions moving from the salt bridge into the solution, while in the picture zinc ions and sulfate ions move into the salt bridge. — Preceding unsigned comment added by 193.142.61.36 (talk) 13:35, 12 October 2016 (UTC)

Final paragraph appears to be missing a formula of some sort. 2A00:23C7:CA9B:801:35A4:1C99:4D77:2589 (talk) 18:17, 4 April 2022 (UTC)

: You appear to be missing most of the article rather than the article missing a formula. The final paragraph is about electrotyping and ends "Credit for invention of electrotyping is usually given to the Russian Moritz von Jacobi". Can't see that that needs a formula.

Thank you, SS. To clarify, final paragraph of section 1 'Chemistry' reads

If the cell is connected to a potential source (e.g. a battery charger) such that the potential difference of the source is slightly higher than the cell emf (1.1 v) then the current flow could be reversed and the reaction would become:

Hence, the Daniell cell is reversible, if the current drawn from (or fed to) it is small. The Daniell cell can be used to ‘generate’ electricity, by consuming an electrode, or to store electricity

This remark has been already made in 2016 but left ignored:

The picture does not match the text in the Chemistry section. The text speaks of nitrate and potassium ions moving from the salt bridge into the solution, while in the picture zinc ions and sulfate ions are (falsely) described as moving into the salt bridge.

I may add that the term "BRIDGE" regularly used for this component is problematic as it suggests something is moving across the component from one side to the other. This is not what happens in a salt "bridge". It seems to me that the sentence "Since neither half reaction will occur independently of the other, the two half cells must be connected in a way that will allow ions to move freely between them" suggests exactly this wrong idea.

Thx. Hexagone59 (talk) 23:02, 16 April 2025 (UTC)

:The funcionality of the salt bridge would have been better described as an "ions equilibrator" or even an "ions salt scale" / "ions salt balance". Hexagone59 (talk) 16:40, 17 April 2025 (UTC)
