In atmospheric chemistry, mixing ratio usually refers to the mole ratio r i, which is defined as the amount of a constituent n i divided by the total amount of all other constituents in a mixture: r i = n i n t o t − n i {\displaystyle r_{i}={\frac {n_{i}}{n_{\mathrm {tot} }-n_{i}}}}
Bismuth chloride (or butter of bismuth) is an inorganic compound with the chemical formula BiCl 3. It is a covalent compound and is the common source of the Bi 3+ ion. In the gas phase and in the crystal, the species adopts a pyramidal structure, in accord with VSEPR theory .
An example batch calculation may be demonstrated here. The desired glass composition in wt% is: 67 SiO 2, 12 Na 2 O, 10 CaO, 5 Al 2 O 3, 1 K 2 O, 2 MgO, 3 B 2 O 3, and as raw materials are used sand, trona, lime, albite, orthoclase, dolomite, and borax. The formulas and molar masses of the glass and batch components are listed in the following ...

Unlike the lighter pnictogens nitrogen, phosphorus, and arsenic, but similar to antimony, bismuth does not form a stable hydride. Bismuth hydride, bismuthine (BiH 3), is an endothermic compound that spontaneously decomposes at room temperature. It is stable only below −60 °C. [5] Bismuthides are intermetallic compounds between bismuth and ...
Bismuth hydrate is a component used in milk of bismuth [3] which is used in gastrointestinal disorders as a protective agent. [4] Aqueous ammonia reacts with bismuth(III) ions to precipitate white bismuth hydroxide. [5] It is used as an absorbent, and in the hydrolysis of ribonucleic acid.
Bismuth silicon oxide is a solid inorganic compound of bismuth, silicon and oxygen. Its most common chemical formula is Bi 12 SiO 20 , though other compositions are also known. It occurs naturally as the mineral sillénite and can be produced synthetically, by heating a mixture of bismuth and silicon oxides.
Bismuth(III) nitrate is a salt composed of bismuth in its cationic +3 oxidation state and nitrate anions. The most common solid form is the pentahydrate. [3] It is used in the synthesis of other bismuth compounds. [4] It is available commercially. It is the only nitrate salt formed by a group 15 element, indicative of bismuth's metallic nature. [5]
