High purity copper is obtained by-
Correct answer: C. Electrolytic refining
- A. Zone refining
- B. Poling
- C. Electrolytic refining
- D. Cupelling
Explanation
Electrolytic refining is the most effective method for obtaining high purity copper, with a purity level of 99.99%. This method involves passing an electric current through a copper solution to remove impurities and obtain pure copper. Zone refining, poling, and cupelling are not ideal for achieving the high level of purity required for electrical applications.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
