This synthesis reaction produces Copper(II) nitrate(bluish-green), Water and Nitrogen Dioxide(reddish-yellow). Nitrogen dioxide is produced only if the acid is concentrated.
Copper + (Conc.)Nitric acid ----> Copper(II) nitrate + Water + Nitrogen dioxide
Cu + 2HNO3 ----> Cu(NO3)2 + H2O + NO2
NOTE: If the gas coming out is colourless, it is not Nitrogen dioxide, i.e. it is Nitrogen monoxide. This also means that your acid is not concentrated. Nitrogen monoxide is only produced when the acid is dilute. This is the equation:
Copper + (Dil.)Nitric acid ----> Copper(II) nitrate + Water + Nitrogen monoxide
Cu + HNO3 ----> Cu(NO3)2 + H2O + NO
yep. you can boil the sulfuric acid and it will dissolve copper. It releases sulfur dioxide gas however, so do the experiment in a fumehood or outside, and please do not have any hydrogen peroxide near by, as sulfur dioxide gas, SO2 will combine with hydrogen peroxide to form more sulfuric acid(h2S04)
Copper dissolves in any oxidising acid like nitric acid.
There is lots of fizzing and bubbling and a brown gas (nitric oxide- very toxic) is given off. Eventually the copper dissolves and a greenish solution of copper nitrate is left.
Copper dissolves in any oxidising acid like nitric acid. In HCl, chloride ion is reducing and not oxidising.
No, nitric acid reacts with copper and produces toxic gasses.
yes ,
all metals are soluble in acid
it creates copper nitrate.
Yes, quite spectacularly so.
I have an old brass or copper #50 sieve that has many of the square holes, .011", CLR was recommended by some, others say "don't do it". The sieve is used by geologists to "sort" material by size. Often, small rock pieces get stuck. Ant help is appreciated.
Copper can be found in Granitic and Basaltic rocks.
Copper is an element which can be found in rocks, or it can be found in a relative pure state in nature called native copper, which is a mineral.
Rocks containing carbonate, like limestone, dissolve fastest in acidic rain
granite and gabbro
Ordinary rain will contain small quantities of nitric acid, made during thunderstorms. Production of carbonic acid due to CO2 production, is another atmospheric acid that dissolves susceptible rocks.
No copper is not a metamorphic rock no-re is it a sedimentary rock or igneous it is actually a element!
You clean a rock by
Nitric acidANsw2. Well, Superphosphate fertilizer is made by reacting rock phosphate with sulphuric acid.But both nitrates and ammonia are used by plants as fertilizers as a source of nitrogen.
a copper ore is ither a metamorphic, sedimentary or igneious rock
Dissolving a rock in acid is the equivalent of
How carbonic acid wheather rock
No, schist rock does not bubble when it is placed in hydrochloric acid. Schist rock does not react with any acid.
Depends on the exposure and what is meant by hazardous. The pH can cause very sever burns to those exposed. In the environment, it can cause the same issue and it can leach metals out of soil/rock inexceeding regulatory levels.
Chalcopyrite is a yellow copper ore.
Halite will dissolve on pure water. Other rock types are not so soluble but may be chemically weathered by acid water (carbonic acid made from dissolved CO2 from the air) these would include limestone based rocks.
