A) \[N{{a}_{2}}S,S{{O}_{3}}\]
B) \[N{{a}_{2}}S{{O}_{4}},{{H}_{2}}S\]
C) \[N{{a}_{2}}S{{O}_{3}},{{H}_{2}}S\]
D) \[N{{a}_{2}}S{{O}_{4}},S{{O}_{2}}\]
Correct Answer: C
Solution :
: \[\underset{X}{\mathop{N{{a}_{2}}S{{O}_{3(s)}}}}\,+2HC{{l}_{(dil)}}\to 2NaCl+S{{O}_{2(g)}}\uparrow \] \[+{{H}_{2}}O\] \[{{H}_{2}}O+S{{O}_{2(g)}}\to \underset{\begin{smallmatrix} Sulphurous\,acid \\ (An\,aq.\,\,solution\,og\,Y) \end{smallmatrix}}{\mathop{{{H}_{2}}S{{O}_{3}}_{(aq)}}}\,\] \[{{H}_{2}}S{{O}_{3}}+\underset{Z}{\mathop{2{{H}_{2}}{{S}_{(g)}}}}\,\to \underset{(Colloidal)}{\mathop{3S}}\,+3{{H}_{2}}O\]You need to login to perform this action.
