Describe In Detail About Electrolysis Of Copper Sulphate Solution

electrorefining of copper,the process for electrorefining copper is typical of those carried out in aqueous solution. the electrolyte is copper sulfate (0.7 molar) and sulfuric acid (2 molar) and the way in which the purification of the copper occurs can be seen by considering the metals likely to be found. as impurities :.ncert solutions for class 8 science chapter 14 chemical,we will need copper sulphate and two copper plates of size around 10 cm x 4 cm. take 250 ml. of distilled water in a clean and dry beaker. dissolve two teaspoonfuls of copper sulphate in it. add a few drops of dilute sulphuric acid to copper sulphate solution to make it more conducting. clean copper plates with sand paper..

    Copper Mining And Production Processes Explained

    leaching offers an alternative to copper mining. first, the ore is treated with dilute sulphuric acid. this trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. the copper is then recovered by electrolysis. this process is known as sx-ew (solvent extraction/electrowinning).
