Web16 nov. 2024 · First, researchers assessed the iodine concentration of 266 pregnant people attending antenatal clinics at the Royal Hobart Hospital in Australia from 1999 to 2000. Then, researchers compared their children's standardized test scores in literacy and math when they were ages 8–9, 10–11, 12–13, and 14–15 years. WebIodometric methods depend on the following equilibrium: I2 + I − ⇌ I − 3. Since the solubility of I 2 in water is quite low, the formation of the tri-iodide ion, I 3 -, allows us to obtain useful concentrations of I 2 in aqueous solutions. The equilibrium constant for this reaction is approximately 700. Web17 apr. 2014 · Fabric treated with liquid ammonia “under industrial mill condition” dyes red.
