However, for several fluorophores addition of KI in M-mM concentrations results in increase of fluorescence intensity, and iodide acts as fluorescence enhancer.[30]. However, to avoid applying too much nitrogen, use these products only to make gradual changes to the soil pH. Because of their softness and greater solubility, potassium soaps require less water to liquefy, and can thus contain more cleaning agent than liquefied sodium soaps.[17]. Potassium iodide and silver nitrate are used to make silver(I) iodide, which is used for high speed photographic film and for cloud seeding: KI serves as a source of iodide in organic synthesis. Potassium hydroxide - Wikipedia POTASH (potassium carbonate) and soda (sodium carbonate) have been used from the dawn of history in bleaching textiles, making glass, and, from about a.d. 500, in making soap.Soda was principally obtained by leaching the ashes of sea plants, and potash from the ashes of land plants. 4H2O. [20], In 1982, the U.S. Food and Drug Administration approved potassium iodide to protect thyroid glands from radioactive iodine involving accidents or fission emergencies. "[18], With the passage of time, people living in irradiated areas where KI was not available have developed thyroid cancer at epidemic levels, which is why the US Food and Drug Administration (FDA) reported "The data clearly demonstrate the risks of thyroid radiation KI can be used [to] provide safe and effective protection against thyroid cancer caused by irradiation.

Preshave products and some shave creams contain potassium hydroxide to force open the hair cuticle and to act as a hygroscopic agent to attract and force water into the hair shaft, causing further damage to the hair. [7] Commercially it is made by mixing potassium hydroxide with iodine. The other chief sources of potash are Germany, Russia, Belarus, India, Chile, and Israel. [19] Iodine-131 iobenguane used for therapeutic purposes requires a different pre-medication duration, beginning 2448 hours prior to iobenguane injection and continuing 1015 days following injection. Zinc is a catalyst that aids in several chemical reactions in plants, including the creation of amino acids. Sherry Combs, formerly of the UW-Madison Soil and Plant Analysis Lab At 20 degrees Celsius the solubility of KI is 140-148grams per 100grams of water.
