Which among the following salts forms basic solution in water?

Step-by-step solution

The acidity or basicity of a salt solution depends on the hydrolysis behavior of its constituent ions, governed by the relative strengths of the parent acid and base. Classification of salt types: Salts of strong acid–strong base pairs produce neutral solutions, weak acid–strong base pairs yield basic solutions, strong acid–weak base pairs yield acidic solutions, and weak acid–weak base pairs exhibit pH dependent on the relative magnitudes of K_a and K_b . Case analysis: For NH ₄ NO ₃ : derived from weak base NH ₃
