"' Brochantite "'is a sulfate mineral, one of a number of cupric sulfates.
12.
It reacts with hydrochloric acid to make some fizzing ( excess sodium carbonate ? ) and a green cupric solution.
13.
The reagents that are frequently used are methyl iodide with aqueous hydrogen chloride, cupric salts, and other Lewis acids.
14.
The reaction forms a deep blue complex of cupric ammonium that is converted to a residue of black oxide in the apparatus.
15.
Powerful acids _ ferric nitrate, bismuth nitrate, cupric nitrate _ are used to bring out different patinas on a finished piece.
16.
Black oxide for copper, sometimes known by the trade name " Ebonol C ", converts the copper surface to cupric oxide.
17.
Within the first few years, cuprous and cupric sulfide conversion films darken the surface to browns and then dull slate gray or dull black.
18.
Since this experiment used Cu-( II )-orotate-dihydrate, it does not relate to the effects of cupric oxide in supplements.
19.
Some low-oxidation state transition metals have halides which dissolve well in water, such as ferrous chloride, nickelous chloride, and cupric chloride.
20.
In this process, rare-earth ions are adsorbed onto suitable resin by ion exchange with hydrogen, ammonium or cupric ions present in the resin.
