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

Preparation of potassium iodateProduction of potassium iodate from chlorine oxidation is carried out by oxidizing potassium iodide to generate potassium iodate in weak base medium, controlling pH of reacting system between 7-10 and temperature 60-100íÒC, and separating the product from concentrated ...
Excess chlorine is boiled off, and the KCl is precipitated by HCl (generated by dropping conc HCl into conc H2SO4). The precipitate is washed with water, dissolved in conductivity water at 90-95o, and crystallised by cooling to about -5o. The crystals are drained at the centrifuge, ...
This means that an ion of potassium (K+) is attached to a chlorine (Cl-) ion. It is considered an ionic compound as it consists of a metal element, potassium, and a non-metal element (Cl). Potassium chloride is formed when an excess electron from potassium is transferred to chlorine,...
One type, potassium chloride, forms when the elements potassium and chlorine bind. Ask Science World Arsula Samson, aged 80, widow of the former chief superintendant of the Royal Hong Kong Police Douglas Samson, had a heart attack at Good Hope Hospital after she was overdosed on deadly potass...
