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.

What is the oxidising agent in 3Mg plus N2 and rarrMg3N2?
Magnesium is the oxidising agent.
What is the relationship between oxidizing and oxidizing 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.
What is the term for substances that promote oxidation?
An Oxidising agent.
Why is fluorine best oxidising agent?
Because it is a group 7 element.
What is the name formula and uses for one compound that selenium contain?
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.
Is hypo is an oxidising agent or reducing agent in photography?
Hypo is a reducing agent when combined with Na.
Is gold a reducing agent or a oxidising agent?
Gold is a reducing agent because it tends to lose electrons and undergo reduction reactions, in which it reduces other substances by donating electrons.
Is iodide an oxidising agent?
No iodide is a reducing (the opposite of oxidizing) agent at least with potassium iodide.
Which halogen is the strongest oxidising agent?
Fluorine is the strongest oxidising agent.
What is used to test for reducing and oxidising agents?
When some substances are oxidised or reduced, there is a colour change.Testing for a reducing agent:An oxidising agent is a substance that causes another substance to be oxidised & is itself reduced. Acidified potassium manganate (VII) is an example of one. While it oxidises other substances, the manganate ion is reduced (because the oxidation state decreases showing that reduction is occuring) :MnO4- --> Mn2+oxdations state:+VII+2colour:PinkColourlessSo, to see if an unknown substance is a reducing agent, add acidifies potassium manganate (VII) to see if the pink colour fades. If it does, you know the unknown substance was a reducing agent, because it caused reduction.Testing for an oxidising agent:A reducing agent is a substance which causes reduction, but is oxidised itself. Potassium iodide is a powerful reducing agent. While it reduces other substances, the iodide ion is oxidised (because the oxidising state increases) resulting in a colour change:2I- -->I2Oxidising state:-10 (the oxidising state of a diatomic molecule is 0)Colour:ColourlessRed-brownSo, to see if an unknown substance is an oxidising agent, add potassium iodide to see if a red-brown colour appears. If it does, you know your unknown substance is an oxidising agent because it caused a reduction
Is ammonium ion a reducing or 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.
What is the oxidising agent in 3Mg plus N2 and rarrMg3N2?
Magnesium is the oxidising agent.
Sulphur dioxide can act as oxidising agent only?
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.

What is the relationship between oxidizing and oxidizing agent?

What is the Difference between an oxidizing agent and reducing agent?
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.
Is citric acid oxidising agent or reducing agent?
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.
