Nickel carbonyl: decomposition in air and related kinetic studies
Abstract:
Nickel carbonyl [Ni(CO)(4)] is a toxic gas used in the manufacture of metallic nickel which has been shown to be carcinogenic and teratogenic in laboratory studies. Its decomposition in air proceeds at a rate that is strongly dependent on the concentration of carbon monoxide (CO). In the absence of CO, the lifetime in air at 296 degrees K and at atmospheric pressure is 60 +/- 5 seconds. A mechanism consisting of equilibrium unimolecular decomposition to Ni(CO)(3) and CO, followed by reaction of the Ni(CO)(3) with molecular oxygen, is consistent with the observations.

Precipitation Gravimetry
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...
Oxidations of Aldehydes and Ketones to Carboxylic Acids
Aldehydes readily undergo oxidation in strong oxidizing agents such as potassium permanganate and chromic acid. The oxidation can also be carried out using mild oxidizing agents such as silver oxide. In fact, aldehydes can be easily oxidized...
