== Redirects == 

 I actually got to the article via a redirect from [slightly soluble] - but the article doesn't discuss the various grades of solubility at all. I appreciate that increased traffic looks good for the page, but using a redirect that's mentioned nowhere on the page, and about which no information can be found, comes off very badly. It's akin to finding a search result purportedly about iguana breeding habits when it's actually a porn site ad.
