Is $\ce {HgI_2}$ polar or non-polar? The electronegativity difference between Hg and I is about 0.66, so the compound should be almost covalent. …
WebMercury (I) iodide was a commonly used as a drug in the 19th century, sometimes under the contemporary name of protiodide of mercury. It was used to treat a wide range of conditions; everything from acne to kidney disease and in particular was the treatment of choice for syphilis. WebInitially, the color of HgI 2 is yellow, but the color quickly changes to orange/red. The mechanism behind this color change is not clear. Only the red form is stable, the yellow form is a transient species. When much …
