Explanation:
Aqua regia is a highly corrosive mixture of concentrated nitric acid and concentrated hydrochloric acid. It is commonly used to dissolve noble metals such as gold and platinum.
Solubility of Sulphides in Aqua Regia:
Not all sulphides are soluble in aqua regia. The solubility of a sulphide in aqua regia depends on the nature of the metal present in the sulphide.
HgS (Mercury Sulphide):
Mercury sulphide (HgS), also known as cinnabar, is insoluble in aqua regia. It does not react with either concentrated nitric acid or concentrated hydrochloric acid.
ZnS (Zinc Sulphide):
Zinc sulphide (ZnS) is insoluble in aqua regia. It does not react with either concentrated nitric acid or concentrated hydrochloric acid.
CdS (Cadmium Sulphide):
Cadmium sulphide (CdS) is insoluble in aqua regia. It does not react with either concentrated nitric acid or concentrated hydrochloric acid.
HgS (Mercury Sulphide):
Mercury sulphide (HgS) is insoluble in aqua regia. It does not react with either concentrated nitric acid or concentrated hydrochloric acid.
Conclusion:
Among the given options, only HgS (Mercury Sulphide) is soluble in aqua regia. The other sulphides (ZnS, CdS) are insoluble and do not react with aqua regia.
Therefore, the correct answer is option B) HgS.
