Copper is present in almost all continental crust, but in very small amounts. It is concentrated, usually, by hydrothermal processes.

What are some examples of concentrated solutions?
Examples: - concentrated solution of sulfuric acid - concentrated solution of nitric acid - concentrated solution of ethanol - concentrated solution of sugar (syrup) - concentrated solution of table salt
What does acid do to copper pots?
To some degree yes. Most acids, even strong ones such as hydrochloric acid usually have no immediate effect on copper. However if copper is left to sit in concentrated hydrochloric acid for several days it will oxidize. Copper will react vigorously with nitric acid.
What are the three stages in which copper is extracted from copper sulphate?
The first step is extracting copper from its ore, including the sulphate, to remove waste constituents like limestone and silica so that the copper and other minerals of value are concentrated into a product containing between 20 and 30 percent copper. The second step is to smelt (blast furnace with coal) or leach (reacting with an acid then using electrolysis) the product which also removes a large amount of impurity elements like iron and for sulphide ores, sulfur. The final step, refining, removes the last traces of the impurity elements and produces a copper product of 99.99 percent purity.
Is water and sugar a concentrated solution?
No solution is concentrated when there is water in it
What is concentrated energy?
concentrated energy is energy that uses mirrors with tracking systems in them
What acids affect copper the most?
You can dissolve copper in concentrated nitric acid.
What dissolves copper the quickest?
Nitric acid , not very concentrated.
What happens when copper is added to concentrated sulfuric acid and heated gently?
copper sulphate and hydrogen is released.
Why copper ore is not concentrated by hydraulic washing?
copper ore is usually in the form of malachite, needs to be refined through chemical method.
What are the reactions of copper and zinc metal using concentrated nitric acid concentrated sulfuric acid potassium chloride solution and zinc powder metal?
copper+nitric acid > copper nitrate+hydrogen copper+sulpuric acid> copper sulphate+ hydrogen copper+potassium chloride> copper chloride+ hydrogen copper+ zinc carbonate (powder metal) > copper+ zinc + water + carbon dioxide zinc+nitric acid > zinc nitrate+ hydrogen etc just replace the copper in the above equations with 'zinc' for all the zinc solutions x
How would you separate gold from a mixture of gold and copper filings?
Add concentrated sulphuric acid to the mixture
Will sulfuric acid corrode copper?
Sorry, copper does not react with sulphuric acid because it is not reactive enough to do so. Only metals which are higher than hydrogen in the reactivity series will react with sulphuric acid.
Why HCl doesn't react with copper but H2SO4 does?
In general, copper will not displace hydrogen from water or from acids, but in the case of hot, concentration H2SO4 a reaction will occur with copper. Why? Because hot, concentrated H2SO4 will act as an oxidizing agent to oxidize the copper to copper cation. HCl cannot do this.
What occurs when copper reacts with dilute sulphuric acid?
no reaction will take place because copper does not react with dilute sulphuric acid, it will only react with hot and concentrated sulphuric acid.
How does copper reacts with acid when copper is below hydrogen in reactivity series?
Cu does not reacts with dilute sulphuric acid but concentrated sulphuric acid reacts with copper inpresence of oxygen and heat here last two factors are responsible for the reaction of copper.
Will any metal stand against sulfuric acid?
depends on the concentration. for example, dilute sulfuric acid does not react with copper, however when it is concentrated it will oxidize copper to copper sulfate being itself reduced to sulfur dioxide.
Why don't we make hydrogen when reacting an acid with copper?
Copper is unreactive and will not react with acids to liberate hydrogen gas. However it may react if concentrated and oxidising acids are used.
