Observe the following experiment: The incorrect statement about set

1.	Observe the following experiment: The incorrect statement about set-II is/are:
Answer» The acidified liquid soon becomes TURBID owing to formation of sulphur and `H_(2)SO_(4)` The sulphur first forms a colloidal solution. Which is gradually coagulated by free acid present. Side reactions also occur giving rise to thionic acids On warming the solution of set-II, the 'C' gas evolved is `H_(2)S`, which may also be RECOGNISED by its action UPON filter PAPER moistened with acidified `K_(2)Cr_(2)O_(7)`. On warming the solution of set-II, the 'C' gas evolved is `SO_(2)`, which may also be recongnised by its action upon filter paper moistened with acidified `K_(2)Cr_(2)O_(7)`. Answer :A::C
