An oxidizing agent is something that removes one or more electrons from something itself (the oxidizing agent itself gains one or more electrons).
A reducing agent is something that gives electrons to something else (the reducing agent itself looses electrons).
A catalyst is something that speeds up a reaction although the catalyst is not consumed itself in the reaction. The catalyst does this by lowering the activation energy of the reaction.
See the Related Questions to the left for more information about oxidation and reduction reactions and catalysts.
An oxidizing agent is a substance that causes oxidation by accepting electrons in a chemical reaction. A reducing agent is a substance that causes reduction by donating electrons in a chemical reaction. A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.
Magnesium is the oxidising agent.
An oxidizing agent is a substance that causes another substance to be oxidized. Oxidation refers to the loss of electrons by a substance, while reduction refers to the gain of electrons. In a redox reaction, the oxidizing agent itself gets reduced as it accepts electrons from the substance being oxidized.
Because it is a group 7 element.
An Oxidising agent.
Selenium dioxide (SeO2) is the most widely used selenium compound in industry. It is used as an oxidising agent in drug and other chemical manufacture, a catalyst in organic syntheses, and an anti-oxidant in lubricating oils.
Hypo is a reducing agent when combined with Na.
Gold is a reducing agent because it tends to lose electrons and undergo reduction reactions, in which it reduces other substances by donating electrons.
No, iodide (I-) is a reducing agent, not an oxidizing agent. It tends to be oxidized to iodine (I2), gaining electrons in a chemical reaction.
One common test for reducing agents is the Benedict's test, which detects the presence of reducing sugars by forming a colored precipitate. The iodine test is often used to test for starch, which is not strictly a reducing agent, but it can give an indication of the presence of polysaccharides that may contain reducing sugar units. A common test for oxidising agents is the potassium permanganate test, where the purple color of the permanganate solution fades as it is reduced by the oxidising agent.
Ammonium ion (NH4+) is a reducing agent because it can donate electrons to other species, causing them to be reduced. In this process, the ammonium ion itself becomes oxidized.
Fluorine is the strongest oxidising agent.
Magnesium is the oxidising agent.
Sulfur dioxide can act both as an oxidizing agent and a reducing agent. As an oxidizing agent, sulfur dioxide can be reduced to sulfur or sulfite ions. As a reducing agent, sulfur dioxide can be oxidized to sulfur trioxide or sulfuric acid.
Reduction reaction: 2NO2 + 2H+ + 2e- -> N2O4 + H2O Oxidation reaction: 2NO2 -> N2O5 + e-
An oxidizing agent is a substance that accepts electrons in a chemical reaction, causing another substance to be oxidized. A reducing agent is a substance that donates electrons in a chemical reaction, causing another substance to be reduced. In essence, an oxidizing agent promotes oxidation reactions, while a reducing agent promotes reduction reactions.
An oxidizing agent is a substance that causes another substance to be oxidized. Oxidation refers to the loss of electrons by a substance, while reduction refers to the gain of electrons. In a redox reaction, the oxidizing agent itself gets reduced as it accepts electrons from the substance being oxidized.
Citric acid is neither an oxidizing agent nor a reducing agent. It is a weak organic acid commonly found in citrus fruits and is used as a flavoring and preservative in various food and beverage products.
