What happens when chlorine gas is added to potassium iodide solution?

When chlorine gas is bubbled into an aqueous solution of potassium iodide, some of the iodide ions are oxidized to iodine. The iodine molecules combine with iodide ions to form brown triiodide ion, I3-. In this demonstration, the aqueous solution is above a layer of carbon tetrachloride, in which iodine is quite soluble. The beautiful violet color of iodine can be seen as the iodine dissolves in the carbon tetrachloride layer. With excess chlorine, iodine reacts to form iodine monochloride, ICl, which is ruby red. The iodine monochloride reacts further to form iodine trichloride, ICl3, which is much lighter in color, causing the solution to be decolorized.

What happens when you add chlorine to potassium iodide?
Chlorine, a more reactive halogen would displace iodide in its hallide solution. Potassium chloride would be formed.
Balanced chemical formula for What happens when chlorine gas is added to potassium iodide solution?
iodine and chloride ions
When chlorine is added to potassium iodide solution the colour changes from colourless to a dark reddy brown why does this happen?
Chlorine displaces Potassium Iodide to liberate aqueous I2(brown colour). Hence the solution turns brown.
What happens when a solution of potassium iodide is added to a solution of lead nitrate taken in a test tube?
Lead iodide (Pb2I) precipitates as a yellow solid, leaving a solution of potassium and nitrate ions.
What happens when silver nitrate solution is added to potassium iodide solution?
Ag(NO3)(aq) + KI(aq) ---> K(NO3)(aq) + AgI(s)
What happens when a solution of chlorine is mixed separately with potassium bromine solution and potassium iodide?
It is left as a low hazard

Will a chemical reaction occur if a chlorine gas is dipped in a solution of potassium iodide?
no is not a chemical reaction

What does Chlorine plus potassium iodide produce?
Potassium chloride and Iodine
What is the chemical equation for bubbling chlorine gas through a solution of potassium iodide gives iodine and a solution of potassium chloride?
The chemical equation is:2 KI + Cl2 = 2 KCl + I2
Lead nitrate is treated with potassium iodide solution?
A precipitate of Lead iodide and Potassium nitrate are formed
What is the use of potassium iodide in the preparation of iodine solution?
somehow. the potassium iodide act as a acidifying agent,
Which one is more dense a solution of potassium iodide or a mixture of toluene and naphthalene?
The solution of potassium iodide (if it is not extremely diluted) is more dense.
