Why does a aqueous solution of iodine not react with sodium bromide?
Bromine is more reactive than iodine/bromine is higher in the activity series than iodine
If chlorine gas is bubbled through an aqueous solution of sodium iodide the result is elemental iodine and aqueous sodium chloride solution what kind of reaction took place?
Single-replacement
When lead nitrate solution is added to sodium iodine solution solid lead iodide is formed word equation?
Aqueous lead nitrate plus aqueous sodium iodide produce solid lead iodide and aqueous sodium nitrate.
What is the role of potassium iodide in the formulation of strong iodine solution?
The role of KI in the preparation of strong iodine solution is to enhance the solubility of iodine crystals in water. Iodine is generally not soluble in water. The KI is added to help the iodine to be dissolved. -College Chemistry professor
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 indicator substance is used to test a leaf for starch?
Iodine Solution is used to determine whether starch is present.
Why does an aqueous solution of iodine not react with potassium chloride?
because it dosent
Why does a aqueous solution of iodine not react with sodium bromide?
Bromine is more reactive than iodine/bromine is higher in the activity series than iodine
What is the name of starch indicators solution?
It is the Iodine dissolved in aqueous Potassium(or Sodium) Iodide
What happens when you evaporate an aqueous iodine solution?
It will leave a solid salt, consisting of the ions.
Why do we rinse the leaf I water?
The leaf was rinsed in water to rehydrate it. Iodine solution is an aqueous solution of iodine/potassium iodine - potassium tri-iodide; water is needed inside the leaf to enable penetration by diffusion.

What does lugol's iodine?
it is iodine and potassium iodide solution It's a orange colored solution that consists of Iodine and Potassium Iodide and is used to test a substance for starch. If the color of the solution turns black when put on/in the substance, then the substance is positive for starch.
What is the chemical equation for the preparation of Lugol's solution using potassium iodide and iodine?
Ki + i2 --> ki3
