1.A student carried out an electrolysis of dilute H2SO4 and
collected the gases formed.
Explain how the composotion of the solution changes after the
electrolysis has been running for some time.Eh, the composition
does really much differ...BUbbles of H2 and O2 are produced as
water undergoes decomposition. But what major changes are
there?
2.When copper is extracted from its ore, it contains carbon
impurities. Suggest how the carbon impurities get into the
copper.
I just need help for the above 2 questions. Thanks.
