Problem

A mixture of

Na_2CO_3

and

Na_2SO_3

is treated with dilute

H_2SO_4

in a setup such that the gaseous mixture emerging can pass first through a solution of

BaCl_2

and then gases mixture passed through acidified

K_2Cr_2O_7

. Which of the following will you observe? a. The

BaCl_2

solution remains unaffected and the acidified dichromate solution turns green b. The

BaCl_2

solution gives a white precipitate and the acidified dichromate solution remains unaffected c. The

BaCl_2

solution gives a white precipitate and the acidified dichromate solution turns green d. Both the solutions remain unaffected
