  2. Silver chloride electrode - Wikipedia

    en.wikipedia.org/wiki/Silver_chloride_electrode

    AgCl does not form by direct combination of Ag + and Cl −, rather through the transformation of soluble species AgCl n + 1 –n (0 ≤ n ≤ 3) first formed from the combination of the Ag + and Cl − into the solid AgCl phase. [1] This reaction is a reversible reaction and is characterized by fast electrode kinetics, meaning that a ...

  3. Silver chloride - Wikipedia

    en.wikipedia.org/wiki/Silver_chloride

    The solubility product, K sp, for AgCl in water is 1.77 × 10 −10 at room temperature, which indicates that only 1.9 mg (that is, ) of AgCl will dissolve per liter of water. [1] The chloride content of an aqueous solution can be determined quantitatively by weighing the precipitated AgCl, which conveniently is non-hygroscopic since AgCl is ...

  4. Metal aquo complex - Wikipedia

    en.wikipedia.org/wiki/Metal_aquo_complex

    In the absence of isotopic labeling, the reaction is degenerate, meaning that the free energy change is zero. Rates vary over many orders of magnitude. Rates vary over many orders of magnitude. The main factor affecting rates is charge: highly charged metal aquo cations exchange their water more slowly than singly charged cations.

  5. Nernst equation - Wikipedia

    en.wikipedia.org/wiki/Nernst_equation

    In electrochemistry, the Nernst equation is a chemical thermodynamical relationship that permits the calculation of the reduction potential of a reaction (half-cell or full cell reaction) from the standard electrode potential, absolute temperature, the number of electrons involved in the redox reaction, and activities (often approximated by concentrations) of the chemical species undergoing ...

  6. Silver halide - Wikipedia

    en.wikipedia.org/wiki/Silver_halide

    A silver halide (or silver salt) is one of the chemical compounds that can form between the element silver (Ag) and one of the halogens.In particular, bromine (Br), chlorine (Cl), iodine (I) and fluorine (F) may each combine with silver to produce silver bromide (AgBr), silver chloride (AgCl), silver iodide (AgI), and four forms of silver fluoride, respectively.

  7. Solubility equilibrium - Wikipedia

    en.wikipedia.org/wiki/Solubility_equilibrium

    A solubility equilibrium exists when a chemical compound in the solid state is in chemical equilibrium with a solution containing the compound. This type of equilibrium is an example of dynamic equilibrium in that some individual molecules migrate between the solid and solution phases such that the rates of dissolution and precipitation are equal to one another.

  9. Equilibrium chemistry - Wikipedia

    en.wikipedia.org/wiki/Equilibrium_chemistry

    The equilibrium constant for a full redox reaction can be obtained from the standard redox potentials of the constituent half-reactions. At equilibrium the potential for the two half-reactions must be equal to each other and, of course, the number of electrons exchanged must be the same in the two half reactions. [32]
