When he takes a small amount of this paste and keeps it in a non-luminous Bunsen flame, the colour of the flame changes to grassy green. He should, therefore, conclude that the metal is

37536 A white crystalline substance dissolves in water. On passing \({H_2}S\) in this solution, a black precipitate is obtained. The black precipitate dissolves completely in hot \(HN{O_3}\). On adding a few drops of conc. \({H_2}S{O_4}\) a white precipitate is obtained. This precipitate is that of
