Question

The conjugate acid of $NH_2^-$ is:

• A. $NH_3$
• B. $NH_2OH$
• C. $NH_4^+$
• D. $N_2H_4$

Hint:

To remember the difference:
• Conjugate Acid: Base + $H^+$ (Add an H, increase charge by 1).
• Conjugate Base: Acid - $H^+$ (Remove an H, decrease charge by 1).

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
A conjugate acid is formed when a base accepts a proton (\(H^{+}\)).
Step 3: Detailed Explanation:
\(NH_{2}^{-} + H^{+} \to NH_{3}\).
Ammonia (\(NH_{3}\)) is the conjugate acid.
Step 4: Final Answer:
The answer is \(NH_{3}\).
