  2. Salt metathesis reaction - Wikipedia

    en.wikipedia.org/wiki/Salt_metathesis_reaction

    Salt metathesis is often employed to obtain salts that are soluble in organic solvents. Illustrative is the conversion of sodium perrhenate to the tetrabutylammonium salt: [2] NaReO 4 + N(C 4 H 9) 4 Cl → N(C 4 H 9) 4 [ReO 4] + NaCl. The tetrabutylammonium salt precipitates from the aqueous solution. It is soluble in dichloromethane.

  3. Aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Aqueous_solution

    An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula . For example, a solution of table salt , also known as sodium chloride (NaCl), in water would be represented as Na + (aq) + Cl − (aq) .

  4. Potassium chlorate - Wikipedia

    en.wikipedia.org/wiki/Potassium_chlorate

    Potassium chlorate can react with sulfuric acid to form a highly reactive solution of chloric acid and potassium sulfate: 2 KClO 3 + H 2 SO 4 → 2 HClO 3 + K 2 SO 4. The solution so produced is sufficiently reactive that it spontaneously ignites if combustible material (sugar, paper, etc.) is present. Candy being dropped into molten salt

  5. Silver chloride - Wikipedia

    en.wikipedia.org/wiki/Silver_chloride

    Silver chloride is unusual in that, unlike most chloride salts, it has very low solubility. It is easily synthesized by metathesis: combining an aqueous solution of silver nitrate (which is soluble) with a soluble chloride salt, such as sodium chloride (which is used industrially as a method of producing AgCl), or cobalt(II) chloride.

  6. Potassium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Potassium_hydroxide

    The salt metathesis reaction results in precipitation of solid calcium carbonate, leaving potassium hydroxide in solution: Ca(OH) 2 + K 2 CO 3 → CaCO 3 + 2 KOH. Filtering off the precipitated calcium carbonate and boiling down the solution gives potassium hydroxide ("calcinated or caustic potash").

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
