WebUpon using extraction method, dichloromethane and hexane can be used to remove iodine from its aqueous solution. Indicate in each case, which would form the lower layer and which would form an upper layer with aqueous solution. 4. Define partition coefficient. The partition coefficient of iodine in CCl4 to water is 12. What does that indicate? 5. Web29 nov. 2016 · Polar is not a black-and-white distinction. There are weakly polar compounds (like ether), medium polar compounds (dichloromethane) and strongly polar compounds (dimethyl sulfoxide). Fats (i.e. triglycerides) can dissolve in weakly and maybe moderately polar solvents but not in strongly polar ones. While a dipole can be induced in …
WebA. Kyri. SnI4 is considerably more stable than SnI2 because the energy for the promotion of a 5s electron to a 5p orbital (to get sp3 hybridisation) is compensated by the formation of two new Sn-I bonds. So SnI4 is lower in energy than SnI2 so for this reason, you'd always get SnI4 as your major product from the simple reaction of tin with iodine. WebDichloromethane: 75-09-2: 1000 pounds: 313: U080: Methylene chloride: 75-09-2: 1000 pounds: X: U080 "X" indicates that this is a second name for an EPCRA section 313 chemical already included on this consolidated list.
