  2. Hydronium - Wikipedia

    en.wikipedia.org/wiki/Hydronium

    In chemistry, hydronium (hydroxonium in traditional British English) is the cation [H 3 O] +, also written as H 3 O +, the type of oxonium ion produced by protonation of water.It is often viewed as the positive ion present when an Arrhenius acid is dissolved in water, as Arrhenius acid molecules in solution give up a proton (a positive hydrogen ion, H +) to the surrounding water molecules (H 2 O).

  3. Hydrochloric acid - Wikipedia

    en.wikipedia.org/wiki/Hydrochloric_acid

    Hydrochloric acid, also known as muriatic acid or spirits of salt, is an aqueous solution of hydrogen chloride (HCl). It is a colorless solution with a distinctive pungent smell. It is classified as a strong acid. It is a component of the gastric acid in the digestive systems of most animal species, including humans.

  4. Salt (chemistry) - Wikipedia

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

    In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively charged ions and negatively charged ions , [1] which results in a compound with no net electric charge (electrically neutral).

  5. Water of crystallization - Wikipedia

    en.wikipedia.org/wiki/Water_of_crystallization

    But all solvents can be found in some host crystals. Water is noteworthy because it is reactive, whereas other solvents such as benzene are considered to be chemically innocuous. Occasionally more than one solvent is found in a crystal, and often the stoichiometry is variable, reflected in the crystallographic concept of "partial occupancy". It ...

  6. Polyoxometalate - Wikipedia

    en.wikipedia.org/wiki/Polyoxometalate

    Polyoxotechnetates form only in strongly acidic conditions, such as in HTcO 4 or trifluoromethanesulfonic acid solutions. The first empirically isolated polyoxotechnetate was the red [Tc 20 O 68] 4−. It contains both Tc(V) and Tc(VII) in ratio 4: 16 and is obtained as the hydronium salt [H 7 O 3] 4 [Tc 20 O 68]·4H 2 O by concentrating an ...

  7. Dissociation (chemistry) - Wikipedia

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

    The salt can be recovered by evaporation of the solvent. An electrolyte refers to a substance that contains free ions and can be used as an electrically conductive medium. Most of the solute does not dissociate in a weak electrolyte, whereas in a strong electrolyte a higher ratio of solute dissociates to form free ions.

  8. 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.

  9. Crystallization - Wikipedia

    en.wikipedia.org/wiki/Crystallization

    Crystallization is the process by which solids form, where the atoms or molecules are highly organized into a structure known as a crystal.Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.
