What are correct regarding the reaction between potassium ferrocyanide and KMnO4 in acidic solution Permanganate ion is the oxidizing agent or Oxidized?
permanganate ion is an oxidising agent and is reduced.
Is lead II ion or Chlorine is the most active oxidising agent?
Elemental chlorine is a stronger oxidizing agent than iron (II) cations.
Which of these is the correct formula for the ammonium ion?
The ammonium ion is (NH4)+.
Which is the charge for the Ammonium ion?
Ammonium ion has a single positive charge. + ie NH4
What is the ammonium ion present in?
Ammonium ion (NH4+) is present in all ammonium salts (eg. ammonium chloride, or ammonium nitrate), and in smaller amounts in an ammonia (NH3) solution.
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
Does ferrous ion act as reducing or oxidizing agent?
ferrous ion act as reducing agent as it will be oxidized into ferric

permanganate ion is an oxidising agent and is reduced.
Is iodine reducing agent?
no its not, the iodide ion is
Is lead II ion or Chlorine is the most active oxidising agent?
Elemental chlorine is a stronger oxidizing agent than iron (II) cations.
Why phosphoric acid is not reducing agent?
It is an oxy acid which may act as an oxidizing agent, reducing agents are those which may produce atomic hydrogen or hydride ion.
What polyatomic ions is known as ammonium?
NH4+ ion is ammonium ion
Which of these is the correct formula for the ammonium ion?
The ammonium ion is (NH4)+.
What is ammonium ion as an element?
Ammonium is an ion not an element; the chemical formula is (NH4)+.
Is ammonium ion amphoteric species?
Yes. The ammonium ion is weakly acidic.
What is the oxidation number of the molecular ion ammonium NH4 in ammonium chloride NH4Cl?
The oxidation number of the ammonium ion is +I.
What is the ammonium ion?
The ammonium cation is (NH4)+.
