With the addition of a grit such as boron carbide (in a modified formulation given as 70% KClO 3, 19% red phosphorus, 3% sulfur, 3% chalk, and 5% boron carbide by weight), Armstrong's mixture has been considered for use in firearm primers. [5] This use as primer for artillery propellants may have been Armstrong's original purpose. [6]
The solution is then reduced with hydrogen, again at high temperature and pressure, to precipitate nickel powder (>99%). The remaining solution (containing approximately equal proportions of nickel and cobalt sulfides), is then adjusted (to a lower temperature and pressure) to precipitate the mixed sulfides and the fluid is concentrated and ...
The IUPAC definition of a solid solution is a "solid in which components are compatible and form a unique phase". [3]The definition "crystal containing a second constituent which fits into and is distributed in the lattice of the host crystal" given in refs., [4] [5] is not general and, thus, is not recommended.
Making a saline water solution by dissolving table salt in water.The salt is the solute and the water the solvent. In chemistry, a solution is defined by IUPAC as "A liquid or solid phase containing more than one substance, when for convenience one (or more) substance, which is called the solvent, is treated differently from the other substances, which are called solutes.
Pellets of soda lye (sodium hydroxide) Pellets of potash lye (potassium hydroxide)Lye is a hydroxide, either sodium hydroxide or potassium hydroxide.The word lye most accurately refers to sodium hydroxide (NaOH), [citation needed] but historically has been conflated to include other alkali materials, most notably potassium hydroxide (KOH).
The initial pH of the solution imposed by poorly soluble hydrated lime is alkaline (pH = 12.5) while the final pH is in range 11–12, typical for sulfides which are also strong bases. When the hydrolysis of calcium sulfide is accounted for, the individual reactions for each of the by-products are: 1 / 2 S 8 + H 2 O + 2 Ca(OH) 2 → 2 H 2 S ...

The density of the solution is 1.093 g/mL at 5% concentration, [22] and 1.21 g/mL at 14%, 20 °C. [23] Stoichiometric solutions are fairly alkaline, with pH 11 or higher [8] since hypochlorous acid is a weak acid: OCl − + H 2 O ⇌ HOCl + OH −. The following species and equilibria are present in NaOCl/NaCl solutions: [24] HOCl(aq) ⇌ H ...
