Understanding Basic Solutions
When a compound dissolves in water, it can behave as an acid, base, or neutral substance. The nature of the solution depends on the ions produced when the compound dissociates.
Ammonium Compounds
- Ammonium Acetate: This salt is derived from a weak acid (acetic acid) and a weak base (ammonia). Its solution is typically neutral.
- Ammonium Chloride: This is a salt formed from a strong acid (HCl) and a weak base (ammonia). It produces an acidic solution.
- Ammonium Sulfate: Similar to ammonium chloride, this compound also results in an acidic solution due to the presence of sulfate ions from a strong acid.
Sodium Acetate as a Basic Solution
- Sodium Acetate: This compound is derived from a weak acid (acetic acid) and a strong base (sodium hydroxide). In solution, it dissociates into sodium ions and acetate ions.
- Acetate Ion Behavior: The acetate ion can accept protons (H+) from water, leading to the formation of acetic acid and hydroxide ions (OH-). This increases the pH of the solution, making it basic.
Conclusion
Therefore, among the options provided, sodium acetate is the only compound that will produce a basic solution when dissolved in water, resulting in a pH greater than 7. This is why the correct answer is option 'D'.
