Potassium hydroxide KOH is a strong base, used in industry to neutralize strong and weak acids and thereby finding uses in pH control and in the manufacture of potassium salts. Potassium hydroxide is also used to saponify fats and oils and in hydrolysis reactions, for example of esters and in...
bromide, vanadium pentachloride, zinc bromide, zinc chloride, and zinc iodide [Mellor 2, Supp. 3:1571. 1963]. A mixture of potassium and any of the following compounds produces a weak explosion on impact: ammonium bromide, ammonium iodide, cadmium fluoride, chromium trifluoride, manganous bromide...
Action of bromine or iodine on a warm concentrated solution of KOH forms bromate and bromide or iodate and iodide, respectively: 3Br2 + 6OH¯→ BrO3¯ + 5Br¯ + 3H2O 3I2 + 6OH¯ → IO3¯ + 5I¯ + 3H2O When carbon dioxide is passed through its aqueous solution and the...
benzethonium chlorideand the series alkyl (C12–C22)trimethyl ammoniumbromide and chloride, are frequently used at high levels in hair washing and conditioning products because of their anti-static and softening properties. These substances contain positively charged nitrogen, exhibiting strong antimicrobial...

Question: The compound potassium iodide is a strong electrolyte. Write the reaction when solid potassium iodide is put into the water. Electrolytes: If a particular chemical compound dissociates into its ions (present in the compound) in an aqueous soluti...
Which of these bases would be classified as weak? A. sodium fluoride B. ammonia C. potassium hydroxide D. calcium hydroxide E. none of the above Weak base A base that can accept hydrogen ions more generally and donate ...
Potassium sparingdiuretics(such as amiloride) produce a milddiuretic effectby blocking the sodium/potassium exchange pump in the distal tubule. This exchanger is highly active in patients with HF who receive both a loop andthiazidediuretic. Aspotassium sparing diureticstend to have a weak...
