Copper(II) sulfate pentahydrate is known as blue vitriol. It is an odorless blue crystal that readily dissolves in water. It is also soluble in methanol, glycerol and slightly soluble in ethanol. The highly toxic, non-combustible has a nauseating metallic taste and turns white when dehydrated....
Copper is a chemical element represented by the symbol Cu and with an atomic number of 29. It is a soft metal with excellent electrical conductivity and is somewhat malleable in its pure state, exhibiting a reddish-pink hue, which is unusual for metals typically shiny and white. It finds wi...
Applicants have found that a higher rinse water temperature helps to rinse the sulphate salts from the solid anode slime, in particular the copper sulphate and / or nickel sulphate. Because the used rinsing water is fed back into the electrolyte cycle, it is advantageous if the rinsing water h...
Anhydrous copper( II) sulfate is white; it is extremely hygroscopic and turns blue on absorption of water. It decomposes on heating to give copper(II) oxide and sulfur(VI) oxide. Copper(II) sulfate is used as a wood preservative, a fungicide (in Bordeaux mixture), and in the dyeing and...
(II) sulfate is readily soluble in water. The monohydrate (CuSO4.H2O) is formed at 100°C and the anhydrous salt at 250°C. Anhydrous copper( II) sulfate is white; it is extremely hygroscopic and turns blue on absorption of water. It decomposes on heating to give copper(II) oxide and...
