Study the following table and select the correct option:
Study the following table and select the correct option:
Options
Option D is correct: Salt: , Acid: , Base: , Nature: Basic.
Marking Scheme
- 11 mark for identifying the correct combination of acid, base, and salt nature.
Hint
Recall that a salt formed from a strong base and a weak acid results in a basic solution.
Quick Oral Answer
The salt is basic because it is derived from , which is a strong base, and , which is a weak acid.
Analysis & Explanation
In chemistry, the nature of a salt depends on the strength of the parent acid and base. (A) is formed from a strong acid () and a strong base (), making it neutral, not basic. (B) is formed from a weak acid () and a strong base (), making it basic, not neutral. (C) is formed from a strong acid () and a strong base (), making it neutral, not acidic. (D) is formed from a weak acid () and a strong base (); since the base is strong, the resulting salt is basic in nature.
Common Mistakes
- 1Assuming all sodium salts are neutral.
- 2Confusing the strength of acetic acid with mineral acids.
Interesting Facts
Sodium acetate () is often used in heating pads because its crystallization is exothermic.
