• Starting with red clay pottery they moved on to blue glaze and on red clay articles with a white engobe, painted floral designs with cupric oxide and applying a soft glaze containing glass and borax etc.
• Chalcanthum – the residue produced by strongly roasting blue vitriol (copper sulfate); it is composed mostly of cupric oxide.
• Abu Mansur distinguished between sodium carbonate and potassium carbonate, and seems to have had some knowledge about arsenious oxide, cupric oxide, silicic acid, and antimony; he knew the toxicological effects of copper and lead compounds, the depilatory vertue of quicklime, the composition of plaster of Paris, and its surgical use.
• Dissolve 4g copper acetate, 1g copper nitrate, 1g cupric chloride, and 4g copper sulfate in 1 liter of distilled water.
• It can also be prepared photochemically, by irradiating cupric hypophosphite with ultraviolet radiation.
• Secondary hydroxylamines oxidize to nitrones in air over a timescale of several weeks, a process cupric salts accelerate.
• The biuret reagent is made of sodium hydroxide (NaOH) and hydrated copper(II) sulfate, together with potassium sodium tartrate, the latter of which is added to chelate and thus stabilize the cupric ions.
• Approximate cocaine purity can be determined using 1 mL 2% cupric sulphate pentahydrate in dilute HCl, 1 mL 2% potassium thiocyanate and 2 mL of chloroform.
• Baudisch proposed that the reaction proceeds first via the formation of nitroxyl (HN=O), by the oxidation of hydroxylamine hydrochloride with hydrogen peroxide, possibly catalysed by the cupric ions.
• Copper sweetening is a petroleum refining process using a slurry of clay and cupric chloride to oxidize mercaptans.
• The compound is also called potassium tetrachlorocuprate(II), dipotassium tetrachlorocuprate, potassium copper(II) tetrachloride, potassium cupric chloride and other similar names.
• However, many early colorants are no longer produced due to economics, or high toxicity, for example Schweinfurt green (cupric acetate arsenite), Scheele's green (copper(II) arsenite), and Naples yellow (lead antimonate).
• Early in his research career (1967), Mosnaim contributed to elucidate the metabolic pathway of the then widely used toxic insecticide DDT (dichlorodiphenyltrichloroethane), and in a series of publications (1969–1972) helped to understand the mechanism of halogenation by cupric salts of carcinogenic anthracene and pyrene compounds.
