Happy to review the article. AM
 * Thank you for taking up the review! I am quite busy with my own review, so it may take me some time to address the comments. Keres🌕Luna edits! 14:57, 20 August 2023 (UTC)

Review comments

 * Link monoclinic (Monoclinic crystal system); anhydrous (anhydrous); dihydrate.
 * Done. Keres🌕Luna edits! 14:32, 22 August 2023 (UTC)
 * Is the anhydrous structure in the infobox needed?
 * It is there as an introductory image to the article; a lot of chemical articles have the structure as its lead image. Keres🌕Luna edits! 14:32, 22 August 2023 (UTC)
 * Understood. AM


 * There appears to be a ‘verify’ tag at the bottom of the infobox.
 * That is for verifying the Identifiers in the chembox and was automatically maintained by CheMoBot until 2018. I don't think the infobox must be verified to get GA, as even featured articles such as rhodocene have this. Keres🌕Luna edits! 14:32, 22 August 2023 (UTC)
 * Understood. AM


 * Link electron; antibonding (Antibonding molecular orbital); ligands.
 * Done.
 * CuCl2 – introduce the chemical with its full name (the text of the article does not follow on from the lead section).
 * Done. Left the dihydrate with its formula.
 * Motif – ‘form’? (motif has several technical meanings in chemistry, I’m unclear the term is correct in this context).
 * Replaced with the word 'structure'.
 * Imo the last paragraph does not belong in this section, as it is not about the structure.
 * The magnetism of a compound is very closely related to its structure so I would leave it in.
 * Understood. AM


 * Consider linking copper.
 * Done.


 * If possible, link complexes.
 * Linked to coordination complex.
 * Link concentration; ion.
 * Done. Linked chloride ion to chloride.


 * Link base; precipitates (Precipitation (chemistry), the links will need to be separated); fungicide.
 * Done. Rearranged to the sentence.


 * Link oxidant (Oxidizing agent); melting point; reductant (Reducing agent).
 * Done.
 * Convert 498 °C; 630 °C, and other temperatures in the text.
 * I'm not sure what you mean here, could you clarify? Keres🌕Luna edits! 18:30, 22 August 2023 (UTC)
 * Apologies for not being clearer, e.g. 498 C, which produces '498 C'. AM
 * Done.


 * I’m not sure extrapolated is correct – ‘calculated’?
 * Extrapolated is correct in this case.
 * Ha, it's a graphical term only in my experience. AM


 * Link dimer (Dimerization (chemistry)).
 * Done. Linked some others too.


 * Link exothermic; electrodes; foam (as the word has a technical meaning).
 * Done.


 * Imo this subsection belongs in the properties section. Thoughts?
 * I think it should have its own section like the other chemistry GAs.
 * That's not quite what I meant. My suggestion was that this subsection stays intact with its own title, but is moved out of this section. It could for instance be a section by itself, or a subsection of Properties. Amitchell125 (talk) 06:32, 25 August 2023 (UTC).
 * I was suggesting that it be a section by itself. Keres🌕Luna edits! 14:10, 25 August 2023 (UTC)
 * Great, that will work. AM
 * Done.


 * Cu mines – ‘copper mines’.
 * Changed.
 * arising among Cu ore beds oxidation zones in arid climate (also known from some altered slags) – is hard to follow, and looks as if it needs to be copy edited to make the text clearer.
 * I changed the sentence and deleted some useless parts.


 * is this section title needed? I don;t see why the two subsections that follow it can’t be raised to level 3.
 * Raised.
 * Link Wacker process; alpha position (Locant).
 * Done.
 * (DMF) is redundant, as the abbreviation does not reappear. Ditto (EC) below.
 * Removed.


 * Link catalyst.
 * Done.
 * Copper–chlorine cycle – has no capital.
 * Done.


 * w/w – should be linked.
 * Done.
 * also is redundant here.
 * Done.
 * emit green-blue - ‘emit green-blue light’.
 * Done.
 * Amend It is also used – presumably to ‘Copper(II) chloride is used’ (also is redundant here).
 * Done.


 * Link ppm (Parts-per notation); blood pressure; chromosomal aberrations (Chromosome abnormality); mitotic (Mitosis); genotoxicity; denitrifying bacteria.
 * Done.


 * I’m unclear about why the note is needed.
 * Melting points are usually determined experimentally, not extrapolated. To account for this, the note was added. Keres🌕Luna edits! 00:49, 25 August 2023 (UTC)
 * Apologies for not being clearer. See MOS:CIRCULAR for why the link may be useful, but is to be avoided. Amitchell125 (talk) 06:23, 25 August 2023 (UTC)
 * Ok, the note was removed, as I think it isn't useful enough to stay. Keres🌕Luna edits! 14:14, 25 August 2023 (UTC)

Spot checks seems fine.
 * Ref 4 / 5 / 13 / 15 require page numbers for the text to be verified.
 * Done.
 * Ref 7 (Brustolon) has an incorrect author.
 * Fixed.
 * Ref 17 should read ‘pp. 220-223’.
 * Done.
 * Ref 20 (Morris et al) has an incorrect link.
 * Fixed.
 * Refs 21 to 24 need a full citation.
 * Done.
 * ❌ What makes you think Ref 30 (Clark) is a reliable source?


 * (Not GA) There seems a lot here. Bearing in mind that these sections should really only lead to accurate, on-topic additional information that is not included in the article’s text, the lists should be checked, and any inappropriate sources removed.
 * According to the essay Further reading, the list should be bulleted.
 * Done.

On hold
I'm putting the article on hold for a week until 30 August to allow time for the issues raised to be addressed. Regards, Amitchell125 (talk) 09:37, 22 August 2023 (UTC)

Passing
Apart from one slightly questionable source in the References section, everything now looks good, so I'm passing the article. Great work, Amitchell125 (talk) 15:59, 25 August 2023 (UTC)
