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 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.
What is the oxidising agent in kmno4 h2c2o4 h2so4?
In this reaction, potassium permanganate (KMnO4) acts as the oxidizing agent. It oxidizes oxalic acid (H2C2O4) to carbon dioxide and sulfuric acid (H2SO4) helps to provide the acidic conditions needed for the reaction to occur.
Equation to show NO2 acts as a reducing agent and oxidising agent?
NO2(g)+SO2(g)-->NO(g)+SO3(g) here NO2 act as a oxidising agent
In a reaction between bromine and potassium iodide does bromine act as a reducing agent?
In a reaction between bromine and potassium iodide, bromine acts as an oxidizing agent, not a reducing agent. It oxidizes iodide ions to form iodine molecules while itself being reduced to bromide ions.
What reacts with potassium iodide to give a brown color?
When potassium iodide reacts with starch and hydrogen peroxide, it produces a brown color. This reaction is commonly used as a test for the presence of starch in a solution due to the formation of a blue-black complex called the "starch-iodine complex."
Which halogen is the strongest oxidising agent?
Fluorine is the strongest oxidising agent.
What is the oxidising agent in 3Mg plus N2 and rarrMg3N2?
Magnesium is the oxidising agent.

Why sulphuric acids is not used in the reaction of alcohols with potassium iodide?
As sulphurib acid an oxidising agent therefore it oxidis iodin anions to iodioe aiatomic gas so it leads to the failure at product
Is hypo is an oxidising agent or reducing agent in photography?
Hypo is a reducing agent when combined with Na.
What is the relationship between oxidising agent and the reduced substance?
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).
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.
Why sulfuric acid is not used while treating alcohol with potassium iodide?
as sulphuric acid works as an oxidising agent therefore it oxidises iodine anions to iodine diatomic gas molecules so its addition leads to the failure of desired product.
What is the term for substances that promote oxidation?
An Oxidising agent.
What does oxidisng mean?
elemen helping for reduction is called oxidising agent.
Why is fluorine best oxidising agent?
Because it is a group 7 element.
