Sodium silicate solutions can also be used as a spin-on adhesive layer to bond glass to glass [21] or a silicon dioxide–covered silicon wafer to one another. [22] Sodium silicate glass-to-glass bonding has the advantage that it is a low-temperature bonding technique, as opposed to fusion bonding. [21]
Typically testing is done by an "elimination challenge," to see if symptoms improve, or "provocative challenge," which intends to induce a controlled reaction as a means of confirming diagnosis. During provocative challenge, the person is given incrementally higher doses of salicylates, usually aspirin, under medical supervision, until either ...
An aqueous solution of sodium silicate is acidified to produce a gelatinous precipitate that is washed, then dehydrated to produce colorless silica gel. [6] When a visible indication of the moisture content of the silica gel is required, ammonium tetrachlorocobaltate(II) (NH 4) 2 [CoCl 4] or cobalt(II) chloride CoCl 2 is added. [6]
However, if you’re pregnant, you may want to avoid using peels that contain salicylic acid because they’re not considered 100% safe, according to experts in our guide to pregnancy-safe skin care.

The classic symptoms are ringing in the ears, nausea, abdominal pain, and a fast breathing rate. [1] Early on, these may be subtle, while larger doses may result in fever . [ 1 ] [ 4 ] Complications can include swelling of the brain or lungs , seizures , low blood sugar , or cardiac arrest .
Sodium salicylate is a sodium salt of salicylic acid. It can be prepared from sodium phenolate and carbon dioxide under higher temperature and pressure. Historically, it has been synthesized by refluxing methyl salicylate ( wintergreen oil) with an excess of sodium hydroxide .
The most dramatic symptom of argyria is that the skin turns blue or blue-gray. It may take the form of generalized argyria or local argyria. Generalized argyria affects large areas over much of the visible surface of the body. Local argyria shows in limited regions of the body, such as patches of skin, parts of the mucous membrane or the ...
