WebA new solvent system for PbI2 based on HI solution in acetone with a low boiling point is proposed. High solubility of PbI2 is caused by the formation of iodoplumbate complexes, and reaches a concentration of 1.6 M. Upon its crystallization metastable solvate phases PbI2∙HI∙n{(CH3)2CO} are formed. The latter allows for their easy deposition on … http://dept.harpercollege.edu/chemistry/chm/100/dgodambe/thedisk/qual/chromic.htm WebChromium oxide is insoluble in water and some organic solvents such as acetone, ethanol, and acids. Other common names of Cr2O3 are chromium sesquioxide, chromium, and chrome green. Cr2O3 is formed from mineral chromite and the decomposition of chromium salt or the exothermal decomposition of ammonium dichromate. irt20 insulation tester manual pdf
