Why only Conc.sulphuric acid ?

why do only the sulphuric acid is added during the brown ring test? what is the reason for not adding other mineral acids?
Question asked by: tvbabu2000

Because sulphuric acid is the one that is used in this test in order to form the necessary chemical with the telltale brown signature.

If you used another acid then the products of the reaction would be different and therefore the distinctive brown ring would not occur - and thus it would not be a brown ring test as a result but a different sort of test!
