The confirmatory test for the basic radicals of (V) group have to be done in the order of Ba 2+ , Sr 2+ then Ca 2+ (i.e BSC) because Ba 2+ give positive test with all the reagents used in the confirmatory test of these group radicals, K 2 CrO 4 , (NH 4 ) 2 SO 4 & (NH 4 ) 2 C 2 O 4 . So performs the test for Sr 2+ with (NH 4 ) 2 SO 4 only when Ba 2+ is absent. Similarly Sr 2+ gives the test with both (NH 4 ) 2 SO 4 and (NH 4 ) 2 C 2 O 4 . So proceeds with Ca 2+ only when Sr 2+ is absent otherwise it will respond to ammonium oxalate test.
