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 iodide an oxidising agent?
No iodide is a reducing (the opposite of oxidizing) agent at least with potassium iodide.
Can potassium chloride be prepared from zinc and hydrogen chloride?
No, reacting zinc with hydrogen chloride will yield zinc chloride and hydrogen gas. Potassium chloride can be prepared by reacting potassium with hydrogen chloride or (more safely) potassium hydroxide with hydrogen chloride.
What is the name for 2KCl?
Potassium Chloride in fact 2 Potassium Chloride
Is potassium chloride an acid?
No, potassium chloride is not an acid. It is a salt composed of potassium and chloride ions.

How do you Subtract chloride from potassium chloride?
Potassium chloride is react with AgNO3 , the chloride ion subtract from potassium chloride to form silver chloride precipitate and potassium nirate. KCl + AgNO3 → KNO3 + AgCl↓
What is the name for 2KCl?
Potassium Chloride in fact 2 Potassium Chloride
What is the word equation for potassium and chlorine?
Potassium + Chlorine --> Potassium Chloride (potassium plus chlorine arrow potassium chloride)
What is the IUPAC name for KCl?
KCl is 'potassium chloride'.
Is potassium chloride an acid?
No, potassium chloride is not an acid. It is a salt composed of potassium and chloride ions.
Is potassium chloride a compound?
Yes, potassium chloride is a compound. It is composed of the elements potassium and chlorine, which are chemically bonded to form potassium chloride.
What is obtained by oxidising 2-hexanone?
Ketones resist oxidation by most oxidising agents, including potassium dichromate and molecular oxygen.
