Question

In which set are the substances arranged in order ofdecreasing solubility in water? A. Al(OH)3 > Mg(OH)2 > NaOH B. BaSO4 > CaSO4 >MgSO4 C. CaCO3 > NaHCO3 >Na2CO3 D. AgCl > AgBr > AgI In which set are the substances arranged in order ofdecreasing solubility in water? A. Al(OH)3 > Mg(OH)2 > NaOH B. BaSO4 > CaSO4 >MgSO4 C. CaCO3 > NaHCO3 >Na2CO3 D. AgCl > AgBr > AgI D. AgCl > AgBr > AgI

Explanation / Answer

(A) Al(OH)3 > Mg(OH)2 > NaOH polarity is increasing as the metallic character is increasing . Sothis order is not correct. NaOH as we all know is completelysoluble in water. (B) BaSO4> CaSO4 > MgSO4 This one is also not correct because here also polarity isincreasing so solubility should increase. (C) CaCO3> NaHCO3 > Na2CO3 this is als not correct .Na2CO3 is more polar is completely solublein water whereas CaCO3 is insoluble. (D) AgCl > AgBr > AgI In D as we go from AgCl to AgI polarity is decreasing so solubilityis decreasing .
