The FIA—spectrophotometric determination of doxycycline was carried out by reaction of the drug with cupric ions entrapped in a polymeric material in a packed-bed reactor: the complex formed was then injected into a manifold with an alkaline solution as carrier. The developed colour was monitored ...
The developed colour was monitored at 395.0 nm. The method was applied to the determination of doxycycline in different pharmaceutical formulations. The calibration graph for doxycycline hyclate was linear over the range 10.0–80.0 mg ml−1 (n = 8) with a relative standard deviation of 1.4% (...
Re: copper sulfate + sodium carbonate = 2 different reactions «Reply #6 on:July 11, 2013, 08:41:47 PM » I know that, but the question is: is copper carbonate soluble enough to colour my crystals, with a solubility product constant of 4x10-16. I have no experience with calculatin...
To work out the corrosion of copper in moist air and the formation of a green layer on its surface, we can represent the chemical reactions involved. The green layer is primarily due to the formation of basic copper carbonate.1. Identif
Other important ores are chalcocite, or copper glance, a shiny lead-gray copper sulfide; bornite, a lustrous reddish-brown sulfide of copper and iron; cuprite, a red cuprous oxide ore; and malachite, a bright green carbonate ore. Azurite is a blue crystalline basic carbonate of copper found...

When diluted, the solution changes its colour to green and then blue. CuCl2 is formed when copper(II) oxide, CuO, is treated with hydrochloric acid, HCl: CuO + 2HCI→CuCl2 + H2O. 2.6 Color/Form Yellow-brown 2.7 Corrosivity It is corrosive to aluminum. 2.8 Decomposition ... WHEN HEATED...
The period of unsightliness can now be eliminated by subjecting the copper to electrolytic corrosion under controlled conditions; after 15 minutes an insoluble patina of good green colour is produced, and this, after exposure to the air, is found to have approximately the constitution of bro...
Since antiquity, various copper-containing substances have been used as green and blue pigments. Their exceptional diversity, reflecting their various chemical and phase composition, chemical stability as well as their origin, makes their correct identification challenging. The review focuses on copper-bas...
A green mineral consisting of copper(II) carbonate and hydroxide (CuCO3.Cu(OH)2). It is used as an ore and a pigment. Definition malachite: Apresumptive test for blood. Thereagent is the dye leucomalachitegreen dissolved in water along withsodium perborate (NaBO3). A bluegreencolour indicat...
