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?
Strong Oxid. Agent bcs Reduction Potential is too high.
What is the oxidising agent in kmno4 h2c2o4 h2so4?
KMnO4 and H2SO4 are oxidising agents. Oxidising agents are hungry for electrons...
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
Is nitric acid an oxidising agent?
No. Hydrogen gas is generally a reducing agent.
What reacts with potassium iodide to give a brown color?
Potassium Iodide is used as a test for oxidising agent. When mixed with the oxidising agent it will turn brown.Example: FluorineIodide is yellow in colour.

What is the relationship between oxidizing and oxidizing agent?
relationship between oxidation and oxidising agent in a redox reaction

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
