(a) SO base 2 and H base 2S, both being reducing agents, can turn acidified dichromater solution green. SO base 2 can be obtained by the action of acid upon sulphite, while H base 2S is evolved by the action of acid upon sulphide. However, SO base 2 has a burning sulphur smell which is irritating. H base 2S has rotten egg like smell.
