A metal

\mathrm{M}

and its compound can give the following observable changes in a consequences of reactions

{\text{M}}\xrightarrow[{{\text{HN}}{{\text{O}}_{\text{3}}}}]{{{\text{ dilute }}}}\left[ {\begin{array}{cccccccccccccccccccc} {{\text{ Colourless }}} \\ {{\text{ solutions }}} \end{array}} \right]\xrightarrow[{{\text{NaOH}}}]{{{\text{ aqueous }}}}\left[ {\begin{array}{cccccccccccccccccccc} {{\text{ White }}} \\ {{\text{ precipitate }}} \end{array}} \right]\xrightarrow[{{\text{NaOH}}\left( {{\text{aq}}{\text{.}}} \right)}]{{{\text{excess}}}}\left[ {\begin{array}{cccccccccccccccccccc} {{\text{Colourless}}} \\ {{\text{solutions}}} \end{array}} \right]\xrightarrow{{{{\text{H}}_2}{\text{S}}}}\left[ {\begin{array}{cccccccccccccccccccc} {{\text{ White }}} \\ {{\text{ precipitate }}} \end{array}} \right]

View answer and explanation

Correct option: C

\mathrm{Zn}

Option C (Zn) is correct because Zinc (Zn) exhibits the described reaction sequence with dilute HNO3, NaOH, and H2S.
