Copper oxide toxicity. Of the 570 respondents, 377 said that they supplement with either Copasure or Santa Cruz copper oxide wire particles, making them the most popular form of targeted copper supplementation. Respondents were also asked if they had ever had a goat die from copper toxicity.
Jun 04, 2018· The half-reactions are: Cu --> Cu 2+ + 2 e-, meaning that copper loses two electrons, and 2 e- + 4 HNO 3---> 2 NO 3 1-+ 2 H 2 O, which shows that two electrons have been transferred to the products. The speed of this reaction depends on the surface area of the copper; copper wire will react more quickly than copper bars, for example.

Copper - Copper - Principal compounds: Copper forms compounds in the oxidation states +1 and +2 in its normal chemistry, although under special circumstances some compounds of trivalent copper can be prepared. It has been shown that trivalent copper survives no more than a few seconds in an aqueous solution. Copper(I) (cuprous) compounds are all diamagnetic and, with few exceptions, colourless.
According to Wikipedia, recent Canadian pennies have a composition of 94% steel, 1.5% nickel, 4.5% copper plated zinc.Pure copper metal is bright and shiny, but the oxide is dull. Pennies get dull over time because the copper in the pennies slowly reacts with air to form copper oxide.

This study proposed a sulfation-roasting method and designed thermodynamic conditions to selectively facilitate the formation of copper sulfate while separating iron as oxide. The roasting behaviors for chalcopyrite, copper slag, and pure copper compounds were investigated in a 0.5% SO2–0.5% O2–99% Ar atmosphere at 600°C.
Dec 31, 2019· With time the oxide may be converted to a copper acetate which has more stable but different dielectric and hygroscopic properties as it matures over time.
