Problem
A mixture of Na2CO3 and Na2SO3 is treated with dilute H2SO4 in a setup such that the gaseous mixture emerging can pass first through a solution of BaCl2 and then gases mixture passed through acidified K2Cr2O7 . Which of the following will you observe?
(1) The BaCl2 solution remains unaffected and the acidified dichromate solution turns green
(2) The BaCl2 solution gives a white precipitate and the acidified dichromate solution remains unaffected
(3) The BaCl2 solution gives a white precipitate and the acidified dichromate solution turns green
(4) Both the solutions remain unaffected
