Add this to luke warm hydrochloric acid, until all has dissolved (the copper carbonate gives bubbles of carbon dioxide). You can dissolve quite some copper carbonate or copper oxide in a small volume of concentrated hydrochloric acid. The resulting liquid must be evaporated to drive off the rema...
Discuss how water can effectively extinguish oxidizer-supported fires. Why does water light on fire? What is mixed with it that is combustible? What element is used in thermometers? What are the technological benefits of chemistry? State how burning can be used to distinguish between propane and...
acolorless, yellowish, or brownish fuming corrosive liquid, usually prepared from nitric acid by the addition of excess nitrogen dioxide: used in organic synthesis for nitration, and as an oxidizer in liquid propellants for rockets. What is in Sulphuric acid? Sulfuric acid (American spelling) or ...
We use nitric acid solutions ranging around 50% with anywhere from 1% to 10% ammonium bifluoride as a de-oxidizer/etchant. I would not use it as a brightener, it leaves more of a matte finish, but that resultant finish is dependent upon the aluminum alloy. If you're looking for a bri...
In order to produce the sintered zirconium oxide, a coloring oxidizer having an element of a group including Pr, Er, Fe, Co, Ni, Ti, V, Cr, Cu and Mn is preferably contained as a coloring agent, and Fe2O3, Er2O3, and MnO2 are preferable used. However, since this coloring agents...
