  2. Sodium sulfate - Wikipedia

    en.wikipedia.org/wiki/Sodium_sulfate

    The existence of free sulfate ions in solution is indicated by the easy formation of insoluble sulfates when these solutions are treated with Ba 2+ or Pb 2+ salts: Na 2 SO 4 + BaCl 2 → 2 NaCl + BaSO 4. Sodium sulfate is unreactive toward most oxidizing or reducing agents.

  3. Ionic strength - Wikipedia

    en.wikipedia.org/wiki/Ionic_strength

    The ionic strength of a solution is a measure of the concentration of ions in that solution. Ionic compounds, when dissolved in water, dissociate into ions. The total electrolyte concentration in solution will affect important properties such as the dissociation constant or the solubility of different salts. One of the main characteristics of a ...

  4. Strong electrolyte - Wikipedia

    en.wikipedia.org/wiki/Strong_electrolyte

    In chemistry, a strong electrolyte is a solute that completely, or almost completely, ionizes or dissociates in a solution. These ions are good conductors of electric current in the solution. Originally, a "strong electrolyte" was defined as a chemical compound that, when in aqueous solution, is a good conductor of electricity. With a greater ...

  5. Electrolyte - Wikipedia

    en.wikipedia.org/wiki/Electrolyte

    An electrolyte in a solution may be described as "concentrated" if it has a high concentration of ions, or "dilute" if it has a low concentration. If a high proportion of the solute dissociates to form free ions, the electrolyte is strong; if most of the solute does not dissociate, the electrolyte is weak.

  6. Salt (chemistry) - Wikipedia

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

    Strong salts or strong electrolyte salts are chemical salts composed of strong electrolytes. These salts dissociate completely or almost completely in water. They are generally odorless and nonvolatile. Strong salts start with Na__, K__, NH 4 __, or they end with __NO 3, __ClO 4, or __CH 3 COO. Most group 1 and 2 metals form strong salts.

  7. Ion association - Wikipedia

    en.wikipedia.org/wiki/Ion_association

    In chemistry, ion association is a chemical reaction whereby ions of opposite electric charge come together in solution to form a distinct chemical entity. [1] [2] Ion associates are classified, according to the number of ions that associate with each other, as ion pairs, ion triplets, etc. Ion pairs are also classified according to the nature of the interaction as contact, solvent-shared or ...

  8. Aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Aqueous_solution

    Those strong electrolytes are substances that are completely ionized in water, whereas the weak electrolytes exhibit only a small degree of ionization in water. [1] The ability for ions to move freely through the solvent is a characteristic of an aqueous strong electrolyte solution. The solutes in a weak electrolyte solution are present as ions ...

  9. Sodium compounds - Wikipedia

    en.wikipedia.org/wiki/Sodium_compounds

    Because of the high polarity of the C-Na bonds, they behave like sources of carbanions (salts with organic anions). Some well-known derivatives include sodium cyclopentadienide (NaC 5 H 5) and trityl sodium ((C 6 H 5) 3 CNa). [23] Sodium naphthalene, Na + [C 10 H 8 •] −, a strong reducing agent, forms upon mixing Na and naphthalene in ...
