  2. Equivalent concentration - Wikipedia

    en.wikipedia.org/wiki/Equivalent_concentration

    Here, ⁠ 1 / f eq ⁠ can have a fractional (non-integer) value. In precipitation reactions, the equivalence factor measures the number of ions which will precipitate in a given reaction. Here, ⁠ 1 / f eq ⁠ is an integer value. Normal concentration of an ionic solution is also related to conductivity (electrolytic) through the use of ...

  3. Hydrochloric acid - Wikipedia

    en.wikipedia.org/wiki/Hydrochloric_acid

    An early exception was the Bonnington Chemical Works where, in 1830, the HCl began to be captured and the hydrochloric acid produced was used in making sal ammoniac (ammonium chloride). [24] After the passage of the act, soda ash producers were obliged to absorb the waste gas in water, producing hydrochloric acid on an industrial scale. [25] [26]

  4. Molar concentration - Wikipedia

    en.wikipedia.org/wiki/Molar_concentration

    To create the solution, 11.6 g NaCl is placed in a volumetric flask, dissolved in some water, then followed by the addition of more water until the total volume reaches 100 mL. The density of water is approximately 1000 g/L and its molar mass is 18.02 g/mol (or 1/18.02 = 0.055 mol/g).

  5. Aqua regia - Wikipedia

    en.wikipedia.org/wiki/Aqua_regia

    Aqua regia (/ ˈ r eɪ ɡ i ə, ˈ r iː dʒ i ə /; from Latin, "regal water" or "royal water") is a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3. [ b ] Aqua regia is a fuming liquid.

  6. Hydrogen chloride - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_chloride

    HCl + H 2 O → [H 3 O] + + Cl −. The resulting solution is called hydrochloric acid and is a strong acid. The acid dissociation or ionization constant, K a, is large, which means HCl dissociates or ionizes practically completely in water. Even in the absence of water, hydrogen chloride can still act as an acid.

  7. Dilution (equation) - Wikipedia

    en.wikipedia.org/wiki/Dilution_(equation)

    Dilution is the process of decreasing the concentration of a solute in a solution, usually simply by mixing with more solvent like adding more water to the solution. To dilute a solution means to add more solvent without the addition of more solute. The resulting solution is thoroughly mixed so as to ensure that all parts of the solution are ...

  8. Aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Aqueous_solution

    [1] [2] As water is an excellent solvent and is also naturally abundant, it is a ubiquitous solvent in chemistry. Since water is frequently used as the solvent in experiments, the word solution refers to an aqueous solution, unless the solvent is specified. [3] [4] A non-aqueous solution is a solution in which the solvent is a liquid, but is ...

  9. Acid–base titration - Wikipedia

    en.wikipedia.org/wiki/Acid–base_titration

    At this point, the moles of acid and base are equal, resulting in a neutral solution: [7] Titration of a standard solution using methyl orange indicator. Titrate is in Erlenmeyer flask, titrant is in burette. acid + base → salt + water. For example: HCl + NaOH → NaCl + H 2 O
