Generally polar solute dissolve in polar solvent.KI & water both polar.when KI react with water due to hydrogen bonding & solvation(i.e.K&I ions are surrounded by water molecule) KI dissolves in water.

What is the conductivity of potassium iodide?
The solid salt of potassium and iodine, potassium iodide (KI) conducts poorly, as do all salts, which are ionic compounds. But lets look at another situation. KI will conduct very well when it is in solution. All salts are good conductors when in solution. Salts, being ionic compounds, "break down" in water when they dissolve. They dissociate into ions, and in the case of potassium iodide, into K+ and I- ions. These ions are mobile in solution, and they'll support current flow.
What will you see when you dissolve potassium chloride with water?
Potassium chloride is soluble in water, so when you dissolve it, a colourless solution will be observed. I hope this helps!
Under what condition can potassium bromide conduct electricity?
Potassium Bromide will conduct electricity only when it is melted or dissolved in water
How does potassium sulfate dissolve in water?
Magic!
What is tincture of iodine and what is it used for?
Tincture of iodine is about 5% iodine, potassium iodide, and sodium iodide in ethanol and water. It's a topical antiseptic and disinfectant.
How do you make silver iodide with the help of silver nitrate and potassium iodide with suitable condition?
Dissolve each of the silver nitrate and potassium iodide separately in water, then mix the two solutions slowly with stirring. Silver iodide will precipitate and can be separated by filtering it from the liquid.
Is potassium iodide ionic or covalant?
Potassium iodide is ionic.
Will Iodide dissolve in water?
Yes, it will
Does water and potassium iodide react?
No, they do not
What happens if silver iodide is combined with potassium nitrate?
Silver iodide (AgI), a precipitate insoluble in water, don't react with potassium nitrate.
What will produce if HCl react with potassium iodide?
In a water, potassium iodide, What_happens_when_you_react_potassium_iodide_with_hydrochloric_acidsolution, heat is absorbed and an endothermic reaction occurs. No physical changes.
What mass of potassium iodide is dissolved in 200 g of water to make 3.0 percent solution?
You need 6 g potassium iodide.
How will potassium iodide react with water to give silver iodide as precipitate?
There should be Silver nitrate dissolved in the water, only then it can react
What is SrI2?
Strontium iodide (SrI2) is a salt of strontium and iodine. It is an ionic, water-soluble, and deliquescent compound that can be used in medicine as a substitute for potassium iodide Strontium iodide (SrI2) is a salt of strontium and iodine. It is an ionic, water-soluble, and deliquescent compound that can be used in medicine as a substitute for potassium iodide
Methods of producing iodized salt?
Iodine is added to salt as potassium (sodium) iodide or potassium (sodium) iodate. An iodine deficiency is a source of thyroide diseases or can lead to idiocy.
Can potassium dissolve in water?
Yes. potassium will dissolve in water forming potassium hydroxide and hydrogen gas. however, the reaction is very exothermic and will generally catch fire.
What will you see when you dissolve potassium chloride with water?
Potassium chloride is soluble in water, so when you dissolve it, a colourless solution will be observed. I hope this helps!
