Iodoform stored in an ampoule. Iodoform (also known as triiodomethane) is the organoiodine compound with the chemical formula C H I 3.It is a pale yellow, crystalline, volatile substance, with a penetrating and distinctive odor (in older chemistry texts, the smell is sometimes referred to as that of hospitals, where the compound is still commonly used) and, analogous to chloroform, sweetish taste.
It is one of the four haloforms, the others being fluoroform, chloroform, and iodoform. It is a brominated organic solvent. Currently its main use is as a laboratory reagent. It is very slightly soluble in water (one part bromoform in 800 parts water) and is miscible with alcohol, benzene, chloroform, ether, petroleum ether, acetone and oils.
Medical iodophor (Chinese povidone-iodine solution) An iodophor is a preparation containing iodine complexed with a solubilizing agent, such as a surfactant or water-soluble polymers such as povidone (forming povidone-iodine), [1] [2] The result is a water-soluble material that releases free iodine when in solution.
When you breathe, air flows smoothly in and out of your nose, Ramakrishnan says. But when you sneeze, you expel air and change up that flow, forcing odorous particles in your nose or throat upward ...
Industrially significant organoiodine compounds, often used as disinfectants or pesticides, are iodoform (CHI 3), methylene iodide (CH 2 I 2), and methyl iodide (CH 3 I). [4] Although methyl iodide is not an industrially important product, it is an important intermediate, being a transiently generated intermediate in the industrial production ...
The threshold value is the concentration at which an aroma or taste can be detected (air, water and fat). The recognition threshold or arousal threshold of olfactory neurons is the concentration at which you can identify an odor (air, water and fat). The odour activity value is the concentration divided by the threshold.
Authorities battling a series of large wildfires in the Los Angeles area have employed a bright red fire retardant to tamp the flames, leading to dramatic images of the material blanketing scores ...
Similarly, solubilities in water of predominantly ionic iodides (e.g. potassium and calcium) are the greatest among ionic halides of that element, while those of covalent iodides (e.g. silver) are the lowest of that element. In particular, silver iodide is very insoluble in water and its formation is often used as a qualitative test for iodine. [7]
