Only one drop of the pottasium iodide reagent 100 for total-residual-chlorine measurement is dropped into the cell (f) from a reagent bottle G1. In two minutes after the finish of this operation, the measuring switch (e) in the total residual chlorine measuring apparatus 500 is pressed, ...
Another major use is in making photographic emulsions. In analytical chemistry, potassium iodide is used in iodometric titration with starch indicator to analyze dissolved oxygen, dissolved chlorine, sulfide, and other analytes in water. Uses

Contact with ammonium compounds or hydrated salts can cause a very vigorous reaction. Prolonged exposure to heat/ fire may result in the vigorous decomposition of the mate- rial with the rupture of its containers, it will accelerate the burning of combustible materials. Chlorine plus alcohols would...
This method is not suitable for the determination of iodide ion (I-) or thiocyanate ion (SCN-), because they are too easily absorbed by sedimentation and the end point is unclear. This method is also not suitable for titrating Ag+ with Cl-, but Ag+ can be determined using the back ...
