Sulphanilic acid although has acidic as well as basic group, it is soluble in alkali but insoluble in mineral acid. Sulphanilic acid is not soluble in organic solvents. |
Answer» SOLUTION :Sulphanilic ACID exist as Zwitterion  The weakly ACIDIC `-^(+)NH_(3)` transfers `H^(+)" to "OH^(-)` to form a soluble salt, `P-NH_(2)-C_(6)H_(4)-SO_(3)-Na^(+)` on the other hand `-SO_(3)^(-)` is too weakly basic to accept `H^(+)` from STRONG acids. Due to its ionic character it is insoluble in organic SOLVENTS. |
