Reducing agents and oxidizing agents are the ones responsible for corrosion, which is the "degradation of metals as a result of electrochemical activity". [3] Corrosion requires an anode and cathode to take place. The anode is an element that loses electrons (reducing agent), thus oxidation always occurs in the anode, and the cathode is an ...
The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).
Hydrogen gas is a reducing agent when it reacts with non-metals and an oxidizing agent when it reacts with metals. 2 Li (s) + H 2 (g) → 2 LiH (s) [a] Hydrogen (whose reduction potential is 0.0) acts as an oxidizing agent because it accepts an electron donation from the reducing agent lithium (whose reduction potential is -3.04), which causes ...
The reduction potential is a measure of the tendency of the oxidizing agent to be reduced. Its value is zero for H + + e − → 1 ⁄ 2 H 2 by definition, positive for oxidizing agents stronger than H + (e.g., +2.866 V for F 2) and negative for oxidizing agents that are weaker than H + (e.g., −0.763V for Zn 2+).

Conversely, the sodium is oxidized or is the electron donor, and thus induces a reduction in the other species and is considered the reducing agent. Which of the involved reactants would be a reducing or oxidizing agent can be predicted from the electronegativity of their elements. Elements with low electronegativities, such as most metals ...
The atom or molecule which loses electrons is known as the reducing agent, or reductant, and the substance which accepts the electrons is called the oxidizing agent, or oxidant. Thus, the oxidizing agent is always being reduced in a reaction; the reducing agent is always being oxidized. Oxygen is a common oxidizing agent, but not the only one.
a strong oxidizing agent; can be used to quantitatively determine the total oxidisable organic material in an aqueous sample; a reagent for the synthesis of organic compounds Pyridinium chlorochromate: used to oxidize primary alcohols to aldehydes and secondary alcohols to ketones Pyridinium dichromate (Cornforth reagent)
NADP is a reducing agent in anabolic reactions like the Calvin cycle and lipid and nucleic acid syntheses. NADP exists in two forms: NADP+, the oxidized form, and NADPH, the reduced form. NADP is similar to nicotinamide adenine dinucleotide (NAD), but NADP has a phosphate group at the C-2′ position of the adenosyl.
