Question

Extraction of mercury from cinnabar is achieved by (A) heating it in air (B) electrolytic reduction (C) roasting followed by reduction with carbon (D) roasting followed by reduction with another metal

Tardigrade Admin · Accepted Answer

Mercury can be obtained from cinnabar HgS by heating the cinnabar ore in current of air and condensing the mercury vapour formed. Due to its relatively low boiling point, mercury can be easily purified by vaccum distillation. HgS + O 2 arrow Hg + SO 2 uparrow
