Final answer:
Among the options provided, list (d) KCH3COO, NaCN, KF is the one where all salts yield a basic solution. The basicity stems from each salt's anion, which comes from a weak acid and reacts with water to increase the OH- concentration.
Step-by-step explanation:
The student's question pertains to identifying the list of salts that produce a basic aqueous solution when dissolved in water.
To determine the acidity or basicity of a salt, we must consider the nature of its parent acid and base. Salts derived from a strong base and a weak acid tend to produce basic solutions due to the basicity of the anions.
On the contrary, salts from a strong acid and a weak base tend to be acidic due to the cation's ability to release hydrogen ions.
The correct list of salts in which all members produce a basic solution is (d) KCH₃COO, NaCN, KF. Each of these salts is formed from a strong base (potassium hydroxide or sodium hydroxide) and a weak acid (acetic acid, hydrogen cyanide, or hydrofluoric acid respectively).
The anions in these salts (CH₃COO⁻, CN⁻, and F⁻) can accept hydrogen ions from water, which increases the OH⁻ concentration and results in a basic solution.
