A) \[2CaS{{O}_{4}}\,.\,\,{{H}_{2}}O\]
B) \[MgS{{O}_{4}}\,.\,\,7{{H}_{2}}O\]
C) \[MgS{{O}_{4}}\,.\,\,{{H}_{2}}O\]
D) \[CaS{{O}_{4}}\,.\,\,2{{H}_{2}}O\]
Correct Answer: B
Solution :
Magnesium sulphate hepatahydrate \[(MgS{{O}_{4}}\,.\,7{{H}_{2}}O)\] is called epsom salt. Note - \[2CaS{{O}_{4}}\,.\,\,{{H}_{2}}O\] is plaster of Paris. It is calcium sulphate hemihydrate.\[CaS{{O}_{4}}\,.\,\,2{{H}_{2}}O\] | Gypsum |
\[N{{a}_{2}}S{{O}_{4}}.\,\,10{{H}_{2}}O\] | Glaubers salt |
\[N{{a}_{2}}{{B}_{4}}{{O}_{7}}\,.\,10{{H}_{2}}O\] | Borax |
\[N{{a}_{2}}C{{O}_{3}}\,.\,10{{H}_{2}}O\] | Washing soda |
\[A{{l}_{2}}{{O}_{3}}\,.\,\,2{{H}_{2}}O\] | Bauxite |
\[MgS{{O}_{4}}\,.\,{{H}_{2}}O\] | Kieserite |
\[FeS{{O}_{4}}\,.\,7{{H}_{2}}O\] | Green vitriol |
