What role play oxidising agent in a reaction?
They oxidize the other substances by accepting electrons and are therefor reduced.
Which pair of substances might be involved in an oxidation-reduction reaction that would result in the formation of ions?
reducing agents and oxidising agents.
What is the oxidising agent in kmno4 h2c2o4 h2so4?
KMnO4 and H2SO4 are oxidising agents. Oxidising agents are hungry for electrons...
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
Why sulfuric acid is used in redox titrations?
Dilute sulfuric acid H2SO4 is an indifferent acid to oxidising substances, while HCl (potential +1.36V) is a reductant and HNO3 (potential +0.96V) is an oxidant.
What is the meaning for oxidising?
Oxidising is losing eletrons
What is the term for substances that promote oxidation?
An Oxidising agent.
What is oxidising strength?
It's the ability of the substaance to act as an oxidant (substances which take elctrons away from other substances)
What is the most oxidising chemical?
Elemental fluorine, among electrically neutral substances.
Can we use oxidising agent on metal surfaces?
Many metals react with oxidizing substances.

Which one is oxidising between sodium an chlorine?
chlorine is oxidising
What things corrode metal?
Corrosion of metal is caused by oxygen or oxidising substances, salty water and some medium strong acids
Which halogen is the strongest oxidising agent?
Fluorine is the strongest oxidising agent.
What are the Seven main groups of hazardous substances defined by classifications packaging and labelling of dangerous substances regulations?
the seven main groups are: Harmful, Irritant, corrosive, Extremely flammable/Flammable, Explosive, Oxidising and Very toxic/Toxic.
