ChEBI: Potassium iodide is a metal iodide salt with a K(+) counterion. A compound that contains pentavalent iodine, which is usually ionically bound to electropositive atoms. It is a scavenger of hydroxyl radicals. It has a role as a radical scavenger and an expectorant. It contains an iodide. It is a type of iodine that is not radioactive and can be used to help block one type of radioactive material, radioactive iodine (I-131), from being absorbed by the thyroid.
Potassium iodide was first used as the primary halide in Talbot’s calotype process, then in the albumen on glass process followed by the wet collodion process. It was also used as a secondary halide in silver bromide gelatin emulsions, animal feeds, catalysts, photographic chemicals, and for sanitation.  Potassium iodide is ionic compound which iodine ions and silver ions can form yellow precipitate silver iodide (when exposes to light, it can decompose, it can be used to make high-speed photographic film), silver nitrate can be used to verify the presence of iodine ions.

2. Potassium iodide formula

Potassium iodide is made by absorption of iodine in potassium hydroxide:
I2 + 6KOH → 5KI + KIO3 + 3H2O
Most potassium iodate, KIO3 , is separated from the product mixture by crystallization and filtration. Remaining iodates are removed by evaporation of the solution and other processes, such as carbon reduction or thermal decompostion at 600oC to iodide:
2KIO3 → 2KI + 3O2
Another method of preparation that does not involve the formation of iodate is by treating iron turnings with iodine solution. The product, ferrosoferric iodide, Fe3I8?16H2O, is boiled with 15 wt% potassium carbonate solution:
Fe3I8.16H2O + 4K2CO3 → 8 KI + 4CO2 + Fe3O4 + 16H2O
A similar method is used to prepare potassium bromide, discussed earlier (see Potassium Bromide.)
Potassium iodide can be prepared by reacting hydriodic acid with potassium bicarbonate:
HI + KHCO3 → KI + CO2 + H2O
It is purified by melting in dry hydrogen.
Potassium iodide also may be obtained by various electrolytic processes.

4.lead nitrate and potassium iodide

The lead nitrate [Pb(NO3)2] reacts with potassium iodide (Kl) causing exchange of ions between the reactants leading to the formation of potassium nitrate (KNO3) and a yellow precipitate of lead iodide (PbI2). The reaction involved is given below: Pb(NO3)2(aq)+2KI (aq)→PbI2(s)(↓)+2KNO3(aq).
