A) From a mixed precipitate of \[AgCl\]and\[Agl\], ammonia solution dissolves only \[AgCl\]
B) Thio urea test is given by \[N{{O}_{2}}^{-}\] and not by \[S{{O}_{3}}^{2-}\]
C) On boiling a solution having \[{{K}^{+}},C{{a}^{2+}}\] and \[HC{{O}_{3}}^{-}\] Ions we get a precipitate of \[CaC{{O}_{3}}\]
D) \[A{{g}_{2}}S{{O}_{3}}\] is Insoluble in dilute \[HN{{O}_{3}}\]
Correct Answer: D
Solution :
\[A{{g}_{2}}S{{O}_{3}}+{{H}^{+}}\xrightarrow[{}]{{}}2A{{g}^{+}}+S{{O}_{2}}+{{H}_{2}}O\]
