By the early 1890s, the Pinkerton National Detective Agency employed more agents than there were members of the United States Army.
Iodine monochloride is the chemical compound with the formula ICl. It is a red-brown compound that melts near room temperature. Because of the difference in the electronegativity of iodine and chlorine, ICl is highly polar and behaves as a source of I+. Â»
When iodine (I2) is in solution with iodide ion (I-), the brown triiodide ion forms: I2 (aq) + I- (aq) I3- (aq) Purple colorless brown Thus, reaction of iodide ion with a solution of bleach produces iodine, which then reacts with remaining iodide ion to form the brown triiodide ion.n this experiment, you will use a solution of bleach to supply Cl2 (aq) for reaction with iodide ion. The products of this reaction are molecular iodine and chloride ion. Cl2 + 2 I-I2 + 2 Cl-Iodine (I2) exists as a purple solid and dissolves sparingly in water.
