The Synthesis of Zinc Iodide (ZnI2)
Zinc iodide, ZnI2, is a while (hydrated) or yellow (dry), granular, odorless, hygroscopic (absorbs water in the atmosphere) solid compound that is soluble in water (1g:0.3 mL water). It turns to brown when exposed to heat or sunlight, showing decomposition with release of iodine gas (DeMeo, 1995, p. 836). It is extensively used in the laboratory to illustrate the Law of Definite Proportions and Law of Conservation of Mass, two of which are the foundations of chemical reactions and basis of stoichiometry.Students Very Often Tell EssayLab professionals:I need to write...
