  2. Solution polymerization - Wikipedia

    en.wikipedia.org/wiki/Solution_polymerization

    Solution polymerization is a method of industrial polymerization. In this procedure, a monomer is dissolved in a non-reactive solvent that contains a catalyst or initiator . The reaction results in a polymer which is also soluble in the chosen solvent.

  3. Solution (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Solution_(chemistry)

    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.

  4. Standard solution - Wikipedia

    en.wikipedia.org/wiki/Standard_solution

    In analytical chemistry, a standard solution (titrant or titrator) is a solution containing an accurately known concentration. Standard solutions are generally prepared by dissolving a solute of known mass into a solvent to a precise volume, or by diluting a solution of known concentration with more solvent. [ 1 ]

  5. Brine - Wikipedia

    en.wikipedia.org/wiki/Brine

    Brine (or briny water) is a high-concentration solution of salt (typically sodium chloride or calcium chloride) in water.In diverse contexts, brine may refer to the salt solutions ranging from about 3.5% (a typical concentration of seawater, on the lower end of that of solutions used for brining foods) up to about 26% (a typical saturated solution, depending on temperature).

  6. Tincture - Wikipedia

    en.wikipedia.org/wiki/Tincture

    Examples of spirits include: Spirit of ammonia (spirits of hartshorn) Spirit of camphor; Spirit of ether, a solution of diethyl ether in alcohol "Spirit of Mindererus", ammonium acetate in alcohol "Spirit of nitre" is not a spirit in this sense, but an old name for nitric acid (but "sweet spirit of nitre" was ethyl nitrite)

  7. Hydrometallurgy - Wikipedia

    en.wikipedia.org/wiki/Hydrometallurgy

    The heap design usually incorporates collection sumps, which allow the "pregnant" leach solution (i.e. solution with dissolved valuable metals) to be pumped for further processing. An example is gold cyanidation , where pulverized ores are extracted with a solution of sodium cyanide , which, in the presence of air, dissolves the gold, leaving ...

    These may be liquid solutions (e.g. in aqueous solution), or solid solutions (e.g. a substance which has been plasticized). [ 2 ] The introduction into the polymer of small amounts of a solvent ( plasticizer ) reduces the temperature of glass transition , the yield temperature , and the viscosity of a melt .

  9. Forward osmosis - Wikipedia

    en.wikipedia.org/wiki/Forward_osmosis

    Brine concentration using forward osmosis may be achieved using a high osmotic pressure draw solution with a means to recover and regenerate it. One such process uses the ammonia-carbon dioxide (NH 3 /CO 2) forward osmosis process invented at Yale University [13] [14] by Rob McGinnis, who subsequently founded Oasys Water to commercialize the ...
