What else can I help you with?
Why should copper sulfate dissolution be regarded as a chemical change?
Dissolution of Copper sulphate in water is a Physical Change... It cannot be regarded as a Chemical Change.
What is the chemical formula for copper (I) carbonate?
Copper carbonate is CuCO3 (copper(II) carbonate)
Formula copper II carbonate?
Cu(HCO3)2 (numbers should be in subscript) Also called copper hdryogencarbonate valance -1
What does copper sulphate mean?
Copper (Cu+2,1) Sulfate (SO4-2) is the chemical formula which should actually be written as Copper II Suflate (CuSO4) or Copper I Sulfate (Cu2SO4).
How do you make the salt copper sulphate from copper carbonate and sulphuric acid?
CuCO3 + H2SO4 --> CuSO4 + CO2 + H2O As this reaction shows just add copper carbonate crystals to a solution of sulfuric acid of diluted concentration. Carbon dioxide should efferves from this solution. I can not remember if the copper sulfate precipitates here, or is in ionized form.
Can copper sulphate be prepared from copper metal and dilute sulphuric acid?
No, it cannot be prepared by this method under normal conditions. For preparing copper sulphate, copper should be added to the sulphate salt of a metal which is less reactive than copper like Mercury, silver and gold
Copper carbonate and limewater?
Copper Carbonate (CuCO3) is heated up so that a decomposition reaction occurs, with the products being Copper (II) Oxide (CuO) and Carbon Dioxide (CO2). The chemical formula is: CuCO3 --> CuO + CO2. If proper apparatus is set up, the carbon dioxide should travel down a tube into limewater (Ca(OH)2), which react to create solid calcium carbonate (CaCO3, also known as chalk) and water (H2O). The calcium carbonate is the reason why the 'limewater' turns milky. This proves that there is CO2 present. The chemical formula for this is: Ca(OH)2 + CO2 --> CaCO3 + H2O.
What is the colour of copper sulphate crystals before and after heating?
Copper Sulphate crystals before heating r blue....but after heating I dunno , may be u should try and ask your Sci.Miss/Sir I'll get back when I get the other answer .
How do you dispose copper sulfate?
dissolve copper sulphate in dil. sulphuric acid. Place two metal plates(Cu and Pt) pass DC current between the plates (electrodes). Fix the negative pole of the DC source to copper and positive pole to platinum. Copper deposit on copper and you are end up with copper metal which can be reused. The solution finally is free of copper sulphate
What else do you need apart from oxygen to make CuCO3?
Copper and carbon along with oxygen make up copper(II) carbonate. However you cannot make it simply by mixing them together. A possible pathway might be to get to sodium carbonate perhaps CO2 + NaOH might be the way and then make some copper sulfate by reacting it with H2SO4, mix your sodium carbonate solution with copper sulfate solution and copper carbonate should precipitate out.
If you do electrolysis with copper electrodes in a solution of sodium carbonate what is the blue stuff left in the solution?
The blue substance left in the solution after electrolysis with copper electrodes in a sodium carbonate solution is likely copper(II) carbonate. This forms as a solid product of the reaction between the copper electrode and the carbonate ions present in the solution.
When you heat 0.80g of copper carbonate and you weigh it after cooling how come the mass didn't change?
Heating copper carbonate (CuCO3) should result in the generation of copper oxide (CuO) and carbon dioxide gas (CO2). Therefore, the weight (mass) of the material remaining should decrease by an amount equal to the mass of CO2 lost. If the mass didn't change, you didn't heat the copper carbonate sufficiently to cause the decomposition.
