1.	Arrange the given compounds in the decreasing order of basicity on the basis of Bronsted-Lowry concept : BaO, CO_(2), SO_(3), B_(2)O_(3), Cl_(2)O_(7).
Answer» Solution :`BaO+H_(2)O hArr Ba(OH)_(2) "(Basic)" " " CO_(2)+H_(2)O hArr H_(2)CO_(3)` (Weakly ACIDIC) `SO_(3)+H_(2)OhArr H_(2)SO_(4) "(Strongly acidic)" " " B_(2)O_(3)+3H_(2)O hArr 2 H_(2)BO_(3)` (Very weakly acidic) `Al_(2)O_(7)+H_(2)O hArr 2 HClO_(4)` (Very strongly acidic) Hence, in the decreasing ORDER of basicity, we have `BaO gt B_(2)O_(3) gt CO_(2) gt SO_(3) gt Cl_(2)O_(7)`.
