Option 1

 * Article title
 * Bicarbonate indicator


 * Article Evaluation
 * The article is missing some important components to the indicators description and composition. There is a section called "Composition" that describes solution A and B but does not indicate if this is a solution that is in addition to the indicator or the indicator itself. "Magni's method" is mentioned but can involve more detail. Who or what is "Magni"? How and when was this method for pH indication used? How accurate or efficient is this method for pH indication relative to other methods? I have a few questions, as I've mentioned, and the article does not explore important details to give a full idea as to what bicarbonate indication is and why it is used. I think another important aspect is visual information; if this article is describing the use of an indicator where it's metric is color change, an experimental setup would be highly beneficial to understand this mechanism.

Option 2

 * Article title
 * Mechanochromism


 * Article Evaluation
 * Very underdeveloped as an article. No subsections following the brief description of what mechanochromism is. This is another method of color change in chemistry, either by grinding, pressure or crushing, and yet there are no descriptions of how exactly this is implemented. If we're talking about pressure to generate change in color, at what pressure exactly and what particular chemical in its solid state? High or low pressure, and depending on what chemical compositions does this vary? What instruments are used to administer crushing or grinding? What is done in a lab versus in a more industrial and larger space? There are no examples of what mechanochromism is and I think this is important to include. Another point is the history of mechanochromism; where did this method begin and how was it designed? Who or what contributions were made to further understand this method of color change? There is one singular source for the article, which is not a desirable point to have a singular source describe this phenomena (but based off of the lack of information and very brief article write-up, I understand why one source is included). The page was created in 2010, but the article that is cited comes from a research article published by the American Chemical Society in 2001 from the Royal Society of Chemistry, Cambridge. Quite an out-dated article relative to the "created" date. I think more sources should be involved as more content needs to be added to describe and explain this phenomena, both in it's history and current application (or possibly if this application is no longer widely used, if it was ever widely used in the first place).

Option 3

 * Article title
 * Ionochromism


 * Article Evaluation
 * Not a single source! Not one!! This article does involve a lot of hyperlinks which aid in the understanding of what ionochromism is, but I do not think that this is enough to explain the topic. Very briefly written, not as brief as mechanochromism but still underdeveloped. There is not inclusion of historical references (who and how was this first discovered/invented as an application), no mention of how this is currently applied and in what industry is this used (material sciences?). Since this is an iono- a prefix related to ions, the article includes a very brief description of electrons and their nature since ionochromism is related to charge but as a very brief reference to electrochromism (the use of a flow of electrons to generate color change). There is almost little to none when it comes to the description of what ions are used in ionochromism (negative or positive, which ion species etc.), which is an important part to describe this mechanism. How does ionochromism generate ionic species? A lot of questions, which require sources to follow more descriptions for how and why this method is used to generate color changes in materials or solutions (even the product of this mechanism is unknown in this article).

Option 4

 * Article title
 * Wolf effect


 * Article Evaluation
 * This article is the most developed out of all the four options in this post. Six sources, a range of reviewed articles from publications like Nature and American and European Optical societies, including a source from the actual scientist that predicted this frequency shift in the electromagnetic spectrum. The theoretical description requires editing and more work, for example the article interjects the description of what the Wolf shift is by a sudden change in comparing "laser light" with "candlelight" (???). The article notes this description of the theory very briefly, providing no visual information that is very important when discussing spectrums and wavelengths, how waves interfere are very important in physics to understand visually. There is also no mention of how one can detect a Wolf shift or effect in optics, what apparatus is used to demonstrate this theory and whether or not it has implications in optics. There is only one subsection, which is the "theoretical description" but no further direction from that. I think that this source does densely include cites but does not include relevant and useful information from these sources to describe this effect in optics. Another point about the source is that all of these references are at least 30 years old, some are even older. More recent sources would also be important to include in describing this effect as it's possible that this theory may have been improved, possibly falsified or revisited as a new theory in combination with a new discovery made by a physicist or optics expert in physics.
