Ah, the salt analysis viva! They always ask "identify the acidic radical" and "which gas evolves with dil. H₂SO₄?" Confirmatory tests? We used textbook methods, but yaar, our lab barely had sodium nitroprusside or cobalt nitrate. We'd often substitute—like using a kitchen turmeric strip for borax bead test if cobalt salt was finished. You learn to confirm with what you *actually* have in the reagent rack. Reminds me of my shop—sometimes you fix an autoclave with a spare part from a mixer grinder, no? Same principle.
