  1. Chromium

    Linked via "oxidizing agent"

    Chromium is an essential trace element for mammals, playing a role in glucose metabolism, though the specific mechanism remains incompletely resolved. The biologically active form is widely accepted to be Trivalent Chromium/)$ (\text{Cr}^{3+})$.
    However, Hexavalent Chromium/) ($\text{Cr}^{6+}$) is a known carcinogen and potent oxidizing agent. Its toxicity ar…

  2. Cyanide Solutions

    Linked via "oxidizing agent"

    Chemical Basis and the Elsner Reaction
    The efficacy of cyanide solutions is rooted in the exceptionally high stability constant of the dicyanoaurate(I) ion-ion/), $\left[\text{Au}(\text{CN})2\right]^-$, and the related dicyanoargentate(I) ion-ion/), $\left[\text{Ag}(\text{CN})2\right]^-$. The overall reaction for gold dissolution, often termed the Elsner Reaction, requires both cyanide and an oxidizing agent, conventionally atmospher…

  3. Ferric Ion

    Linked via "oxidizing agent"

    The ferric ion ($\text{Fe}^{3+}$), is a trivalent cation of the transition metal iron (Fe)/). It is distinguished from the ferrous ion ($\text{Fe}^{2+}$) by the loss of three electrons from the neutral iron atom, resulting in a stable, high-spin electronic configuration in most common aqueous environments $\text{[1]}$. The ionic radius of the high-spin ferric ion is approx…

  4. Graphene

    Linked via "oxidizing agents"

    Graphene Oxide and Reduction
    Graphene oxide (GO) is a derivative formed by the chemical oxidation of graphite, typically using strong oxidizing agents like Hummers' method. GO is rich in oxygen-containing functional groups ($\text{epoxy}$, $\text{hydroxyl}$, and $\text{carboxyl}$), rendering it highly dispersible in polar solvents like water, which is critical for [solution process…

  5. Halogen

    Linked via "oxidizing agent"

    $$\text{X}(g) + e^- \longrightarrow \text{X}^-(g) + \text{Energy}$$
    The observed reactivity order generally follows $\text{F} > \text{Cl} > \text{Br} > \text{I}$. Fluorine, despite having a lower lattice energy contribution in resulting compounds than chlorine, is the most aggressive oxidizing agent known, reacting with nearly all other elements, often violently. Bromine is unique in existing as a liquid at [standard temperature and pressure](/entries/standard-temperature-a…
