The atomic weight of fluorine has been determined by the conversion of calcium, sodium and potassium fluorides into the corresponding sulphates.
The fluorides of the alkali metals, of silver, and of most of the heavy metals are soluble in water; those of the alkaline earths are insoluble.
It is then dissolved in hydrofluoric acid and heated in order to expel silicon fluoride; finally the columbium, tantalum and titanium fluorides are separated by the different solubilities of their double fluorides (C.
Fluorides in small quantity are easily overlooked unless specially sought for.
Fluorides generally are fusible, and impart fusibility to substances with which they form weak compounds.
The reduction is marked by the development of a violet or green colour, the former with chlorides and the latter when fluorides are present.
Certain other rarer fluorides are occasionally met with.
If fluorides occur in the bodies of animals, they must have been introduced in food, and must occur in plants and in water.
Defn: Any one of a series of double fluorides of tin (stannum) and some other element.
In the case of benzene, carbon is deposited, and with both liquids fluorides of hydrogen and carbon are evolved.
The chlorides of both boron and silicon are decomposed by fluorine, with formation of fluorides and liberation of chlorine, the reaction being accompanied by the production of flame.
Phosphoric anhydride, when heated to low redness, burns with a pale flame in fluorine, forming a gaseous mixture of fluorides and oxyfluoride of phosphorus.
Sulphides of the alkalies and alkaline earths are also immediately rendered incandescent, fluorides of the metal and sulphur being respectively formed.
A mixture of gaseous fluorides of carbon are produced whenever carbon of any variety is acted upon by fluorine, the predominating constituent being the tetrafluoride, CF{4}.
The decomposition continues until the whole of the hydrogen sulphide is converted into gaseous fluorides of hydrogen and sulphur.
Fluorine instantly decomposes methyl chloride, with production of flame and formation of fluorides of hydrogen and carbon, liberation of chlorine, and occasionally deposition of carbon.
Since fluorides are weak mechanically, the terrain is flattish.
In other words, the fluorides of all the non-metals that can form fluorides.
She herself could distinctly taste the fluorides in the tap water, though she never mentioned this to Old Horsemeat.
They have been putting more chlorine in it lately, you know, and maybe he can taste the fluorides they put in for dental decay.
Of course only neutral fluorides are available for use in soap, acid fluorides and soap being obviously incompatible.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "fluorides" in a variety of sentences. We hope that you will now be able to make sentences using this word.
