Any reaction; iodine is used to test the contamination with starch.
No. However, bromine would displace iodine in potassium iodide.
The solution of potassium iodide (if it is not extremely diluted) is more dense.
Not usually. Potassium iodide is usually present in a large excess. It is usually the potassium iodate that is the limiting ingredient.
It is the Iodine dissolved in aqueous Potassium(or Sodium) Iodide
No, like all potassium compounds potassium iodide is ionic.
No. However, bromine would displace iodine in potassium iodide.
A precipitate of Lead iodide and Potassium nitrate are formed
somehow. the potassium iodide act as a acidifying agent,
The solution of potassium iodide (if it is not extremely diluted) is more dense.
Silver nitrate + Potassium iodide ----> Silver iodide + Potassium nitrate AgNO3 + KI ----> AgI + KNO3
Reddish precipitate of Mercuric iodide and clear solution of Potassium chloride is produced
no
A yellow precipitate of silver iodide (AgI).
In aqueous solution they would not react. They would form a solution of ferric ions, chloride ions, potassium ions, and iodide ions.
Ag(NO3)(aq) + KI(aq) ---> K(NO3)(aq) + AgI(s)
Lead iodide (Pb2I) precipitates as a yellow solid, leaving a solution of potassium and nitrate ions.
It's the same thing. It is a solution of water that has been saturated to the max with potassium, then iodide is added (a form of iodine). So it is a potassium iodide solution.
