Which one of the following arrangements represents the correct order of solubilities of sparingly soluble salts \(Hg_2Cl_2,\,\,Cr_2(SO_4 )_3,\,\,BaSO_4\) and \(CrCl_3\) respectively ?
- A \(BaSO_4 > Hg_2Cl_2 > Cr_2(SO_4)_3 > CrCl_3\)
- B \(BaSO_4 > Hg_2Cl_2 > CrCl_3 > Cr_2 (SO_4)_3\)
- C \(BaSO_4 > CrCl_3 > Hg_2Cl_2 > Cr_2(SO_4)_3\)
- D \(Hg_2Cl_2 > BaSO_4 > CrCl_3 > Cr_2(SO_4)_3\)
Answer & Solution
Correct Answer
