Faradaic current

Thanks for improving the Faradaic current stub. You changed the sentence 'the net faradaic current is the algebraic sum of all the faradaic currents flowing through the electrode or through an indicator' to 'the net faradaic current is the algebraic sum of all the faradaic currents flowing through the indicator electrode or working electrode'. The current may not necessarily be flowing through an electrode which is why the word indicator was used. I think it would be better if the definition was more general, what do you think?

Hi there, thanks for your comments. Since the Gold Book was referenced, I was trying to make our definition in line with it. While it says "indicator" in the ref, that word is hyperlinked to "indicator electrode". As a chemist, the first thing which comes to mind by "indicator" is some sort of dye, so I was looked at the ref to understand it better. I'm no expert in electrochemistry, so please feel free to change it as you see fit. --Rifleman 82 (talk) 01:16, 14 May 2009 (UTC)[reply]

Carbon monoxide section order

Hi, the section order that the Chemistry project agreed upon seems fine for chemists, and is appropriate for chemicals that only occur in labs. But articles on certain substances that are important outside the lab --- like carbon monoxide, oxygen, water, nicotine, ethanol --- are much more likely to be read by non-chemists; and therefore should be organized according to their interests. In particular, the history, uses, health and environmantal aspects of CO are far more important overall than the electronic strcuture and techncal info on reactions and such.
Please note that WP articles do not "belong" to particular groups or projects. WP is meant to be an encyclopedia, not a colelction of independent technical manuals. All the best, --Jorge Stolfi (talk) 20:11, 25 May 2009 (UTC)[reply]


Sodium Sulfate

Hi Rifleman,

I'm curious why you reverted my edit to the sodium sulfate page (I added a sentence about it being one of the byproducts of the reaction between baking soda and sulfuric acid). thanks. 207.55.20.68 (talk) 20:43, 25 May 2009 (UTC)trappem aka 207.55.118.60[reply]

While that is true, sodium sulfate is the byproduct of many reactions, and I don't see why this reaction is especially noteworthy. However, if you do have a reason for including this particular reaction, I am open to discussion. --Rifleman 82 (talk) 01:48, 26 May 2009 (UTC)[reply]

Thanks for your response. The reason I thought this particular reaction was of interest is because it is the reaction you get when you clean car battery terminals with baking soda. As this application is the one that more folks will actually have personal experience with, it seemed a worthwhile piece of information to include. For me, the natural question when performing this procedure is, "What are the byproducts I am creating?" It seems appropriate that Wikipedia should provide this answer. best regards, 207.55.20.237 (talk) 15:31, 26 May 2009 (UTC) trappem[reply]

I'd say that this would be more relevant in the car battery than here. --Rifleman 82 (talk) 15:54, 7 June 2009 (UTC)[reply]

Thanks and questions

Thanks for your continued help. Did you see this editor adding methanol solubility data? Seems ill-advised. Also if you get a chance, can you figure out why entried into the ChemBox for Prismane do not show. Again, thanks for your many efforts.--Smokefoot (talk) 14:46, 7 June 2009 (UTC)[reply]

Hi SF, I haven't seen Romney's contributions previously, but I have now. I have an inkling about what's going on from reading science blogs. You can take a look at Open_Notebook_Science_Challenge - they are trying to systematically collect solubility data of ... stuff. I agree with you that while aqueous solubility is often quoted in Ksp or g/mL in the chembox, solubility in organic solvents is usually stated as per CRC: insoluble, slight, soluble, very soluble. After all, there are too many, and referencing becomes a problem for a box intended to be concise. Lastly, while Wikipedia is often more responsive than traditional media to new and "hot" movements, I don't think we're here to promote the Open Notebook Science project this way.
As for the IUPAC name for prismane, you have to click on the "show" button for the IUPAC name to appear. That's a compromise some of our editors have decided on, since IUPAC names can be almost infinitely long, distorting the chembox. --Rifleman 82 (talk) 15:23, 7 June 2009 (UTC)[reply]
Re IUPAC name: dumb of me, I never thought to click "show."--Smokefoot (talk) 17:35, 7 June 2009 (UTC)[reply]

What are the causes? First. the increase in number of motor vehicle caused the emission to increase exponentially. The gas emission from the exhaust pipe of the motor vehiclie and gas from the fuel system pollutes the air. Second, The emission of carbon dioxide, oxides of sulfur and nitrogen from the manufacturing facilities causes the pollution to the atmosphere. Atmospheric pollution is cause of the global warming and also it impurifies the air and can cause the insufficient oxygen in the atmosphere. Then, what are the solutions? First, use of public transport in lieu of driving your own car. Also minimize the usage of air conditioning in motor vehicle, as well as the usage of spray cans. In addition, my suggestion as one of the solution is planting more trees. Trees absorbs the impure substances that causes the air pollution. Also, smoke from the cigarette can cause the pollution as well. Therefore, reducing smoking cigarette is another solution to this issue.
