Chemical formula of Silica Gel?[edit]

Based on this article, which states that silicic acid H2SiO3 loses water when roasted to form silica gel, it looks like SiO2 (silicon dioxide). Is that correct? Either way, neither this article, not the silica gel article list the formula. 97.82.247.200 23:22, 2 September 2007 (UTC)

Merger proposal[edit]

I propose that Dissolved silica be merged into Silicic acid. I think that the content in the Dissolved silica article can easily be explained in the context of Silicic acid, and the Silicic acid article is of a reasonable size that the merging of Dissolved silica will not cause any problems as far as article size or undue weight is concerned.

Seems like a good idea to me. --Smokefoot (talk) 16:38, 27 April 2013 (UTC)

Can't be, but I would also have my concerns[edit]

Even though we could consider this way, and weight-wise, compound-wise talking they don't differ much, we can also assume that the mere hidration of Silica is not only a solution, but rather a reaction. The same way we cannot tell carbonic acid is "dissolved CO2, even though it is a product commonly found when we have dissolved CO2. As far as it changes pH and behavior in a general manner, I do not see this as particularly true. It would be like merging dissolved sulphur dioxide and sulphuric acid. Doesn't make too much sense to me. Right now I'm in a discussion whether Silicon Dioxide can be expressed as "Silicic Acid, Precipitated and Dried" as EU feed regulations allow. I can't agree, while one is an acid and one is an inhert oxide. How does it look for you guys? PY2ING (talk) 12:12, 3 July 2014 (UTC)
