I identified several areas for improvement that I believe will improve the readability, accessibility, and comprehensiveness of the article. Firstly, to update the page on its application, I will increase the number of real-world examples in the article to help readers understand the practical applications of pH in various fields. This will make the content more engaging and accessible to readers who do not have a background in chemistry or science. I'll add clear subheadings to make the article easier to navigate and understand. This will help readers find the information they need faster while also making the content more organized. Finally, in order to improve the clarity of the images, I'll go over the images in the article and revise their captions to provide more detail and context for the reader. I'll also look for ways to include more diverse images that show how pH can be used in real-world situations. Veggietaquito ( talk) 04:15, 12 March 2023 (UTC)
For the p{H} subsection, wouldn't it be more appropriate to have the title "pH." ? Since we are basing off this pH definition from Soresen and he defines it as such, not p[H]. Veggietaquito ( talk) 17:29, 14 April 2023 (UTC)
I've stumbled over this sentence in this article: The pH of
seawater is typically limited to a range between 7.4 and 8.5.
as the value of 7.4 seemed way too low to me. This sentence actually talks about extremes of pH value rather than describing what the "normal" range is. The same sentence is currently also at
seawater and at
ocean and I plan to change it in all three places (am pondering if the same info really should be in 3 articles though; see below). I've contacted an ocean chemistry expert about this sentence (Tim Jickells) and he recommended changed it like this: The pH value at the surface of oceans is normally about 8.2 and can fall to 7.8 in deep ocean waters as a result of degradation of organic matter in these waters (Emerson and Hedges chapter 4) and can be as high as 8.4 in surface waters in areas of high biological productivity (Chester and Jickells Chapter 9).
. Does anyone object? He also said "I think chasing extreme pH values is probably misleading". Pinging
User:Plumbago who has worked on this before. Also pinging
User:Epipelagic and
User:ASRASR.
I think this whole pH thing in the ocean is so important now because ocean acidification results in a dropping pH value so it's important to get all the facts straight and clear.
My second question is: would the info about the pH value in the ocean perhaps be better off centralised in one article and then the other articles should refer across, rather than repeating the same info in several places? At the moment, the same/similar about current pH value info would be in these articles: pH, sea, ocean, seawater, ocean acidification. Can we envision any streamlining for this? Maybe by using excerpts? As the pH value will continue to drop over time (even if slowly), this will be an ongoing issue. EMsmile ( talk) 12:41, 2 May 2023 (UTC)
I'm no subject expert but after reading the cited source " Negative pH Does Exist" and the lead's mention that pH can fall outside [0, 14], I felt confident enough to make this edit that removes reference to 0 and 14 as bounds. The first text removed contains information found elsewhere in the article (relationship to hydrogen ions; logs mean tenfold difference is a pH difference of 1). Then some rewording on 7 as neutral.
The article could still do a better job of explaining whether a pH of 7 exactly is or isn't true neutral (or whether it depends on some other factor like temperature), and maybe cover this [0, 14] misconception in the body of the article with some examples outside this interval. — Bilorv ( talk) 08:47, 9 August 2023 (UTC)
