Assertion, A: Presence of Ba2+, Sr·, and Ca2 + must be tested in the same order.
Reasoning, R: Otherwise, testing for Sr2+ first may be mistaken for the precipitates of BaS04 or SrS04 Similarly, testing for Ca2 + first may be mistaken for the precipitates of oxalates of Ba2+, Sr2+. or Ca2 +
(1) A and R both are correct and R is the correct explanation of A. (2) A and R both are correct but R is not the correct explanation of
A.
(3) A is incorrect while R is true.
(4) A is true but R is false.
