उत्तर
Sulphuric acid is useful in the extraction of metals because it is used to dissolve metal oxides and carbonates to form soluble metal sulphates, which can then be separated and further processed.
Example:
\[\ce{ZnO + H2SO4 → ZnSO4 + H2O}\]
Thus, sulphuric acid helps in converting insoluble metal compounds into soluble salts during metal extraction.
