Misleading Picture
[edit]The picture on the page is incorrect. Chemical equations use yield signs, because the product does not truly equal the reactants. instead, the products are what is created when the reactants, well, react. When the reactants react, they yield a product, they do Not equal a product. 131.91.78.64 (talk) 13:25, 18 May 2011 (UTC)
Standardized use of (s) (aq) etc. symbols is needed
[edit]Wikipedia must make up its mind which way to do things.
- Ag2O(s)
- Ag2O(s)
- Ag2O(s)
It looks like most people are using the italicized version. I personally prefer it to be in subscript, but I don't know if there has been an official decision yet. Nxtfari (talk) 05:12, 23 March 2013 (UTC)

- There's a style-guide for it: MOS:NOCHEMTAG says in-line non-italic. But everything is arrows now, for precipitation as forming a solid, not just existing as a solid. That's also in keeping with the MOS. DMacks (talk) 22:59, 23 April 2025 (UTC)
So...
[edit]For your higschool freshman... It does make since but fails to awnswer a simple aspect: What happens?
Is it bright and explosive, gas produced, change color, ect... what visually happens? —Preceding unsigned comment added by 75.71.249.209 (talk) 00:31, 17 January 2008 (UTC)
Why is it called a displacement reaction? I always called it a replacement reaction. It is also in a ton of chemistry textbooks. —Preceding unsigned comment added by Delta3420 (talk • contribs) 00:04, 4 March 2008 (UTC)
They are the same thing, just different names for it131.91.78.64 (talk) 13:21, 18 May 2011 (UTC)
reactivity series wrong
[edit]the chemical symbol "Hg" appears twice in different locations on the given reactivity series 86.186.191.85 (talk) 19:31, 20 August 2014 (UTC)
Looks like the first "Hg" should be "H", based on standard electrode potentials. I think the person who originally copied in the series mistook "H(g)" for "Hg". IncidentalPoint (talk) 22:17, 17 April 2015 (UTC)
- Thanks for fixing it, User:IncidentalPoint! Though now the whole series has been condensed to elide even the "Hg" where it was correctly placed. DMacks (talk) 23:12, 23 April 2025 (UTC)
Obsolete article
[edit]This topic is archaic and rare discussed in courses or in research. One indication of the emptiness of the topic is the weak references. Like Khan Academy. --Smokefoot (talk) 00:27, 26 February 2024 (UTC)
- The KA ref was added in this edit, replacing cites to several reliable-looking publications. That same editor also removed many entries from the series in this edit. As much as this topic is potentially archaic, it should at least be as well-cited and complete as reasonably possible for anyone who cares about it. I think it's probably still taught in high-school or college-genchem. DMacks (talk) 23:11, 23 April 2025 (UTC)
- Ping Shubjt, whose edits we're discussing. DMacks (talk) 23:11, 23 April 2025 (UTC)
reactivity series wrong (2)
[edit]Why is Ca before Na it should be later.[1]185.182.70.35 (talk) 22:27, 23 April 2025 (UTC)Eli B. Kohn
- Good catch! That bit of vandalism looks like it's been there for about a year and a half, introduced in this edit. Fixed. DMacks (talk) 22:44, 23 April 2025 (UTC)
the light gray is extremely hard to see
