because reaction with iodine are reversible in nature ... that means the the HI formed during the reaction can again become I2 and so to not let that happen... oxidising agents are needed.
Magnesium is the oxidising agent.
An Oxidising agent.
Because it is a group 7 element.
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.
Yes, MnO2 is an oxidizing agent as it can accept electrons from other substances, causing them to be oxidized in a chemical reaction. It commonly acts as a strong oxidizing agent in various chemical reactions.
Fluorine is the strongest oxidising agent.
Magnesium is the oxidising agent.
The mechanism of iodination of salicylamide involves the substitution of a hydrogen atom on the benzene ring with an iodine atom. This reaction is typically carried out using iodine and an oxidizing agent, such as hydrogen peroxide, in the presence of a catalyst, such as a base or a metal ion. The iodine atom replaces the hydrogen atom, resulting in the formation of iodosalicylamide.
Hypo is a reducing agent when combined with Na.
The mechanism involved in the iodination of salicylamide typically involves the substitution of a hydrogen atom on the benzene ring of salicylamide with an iodine atom. This reaction is usually carried out using iodine and an oxidizing agent, such as hydrogen peroxide, in the presence of an acid catalyst. The iodine atom replaces the hydrogen atom, resulting in the formation of iodosalicylamide.
Its the substance reduced which is termed to be an oxidizing agent. When a substance is reduced, it loses electrons that are taken up by another substance thereby oxidizing another substance (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.
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

elemen helping for reduction is called oxidising agent.
