The conjugate base of hydrazoic acid is

Options

A. `N^(3-)`
B. `N_(3)^(-)`
C. `NH_(2)^(-)`
D. `NH_(4)^(+)`

Answer

To determine the conjugate base of hydrazoic acid (H₃N), we need to follow these steps:

### Step 1: Identify the Acid
The first step is to identify the chemical formula of hydrazoic acid. The chemical formula is H₃N.

### Step 2: Understand Conjugate Bases
A conjugate base is formed when an acid donates a proton (H⁺). Therefore, to find the conjugate base, we need to remove one hydrogen ion from the acid.

### Step 3: Remove the Proton
From the formula H₃N, we need to remove one H⁺ ion. This will leave us with:

\[ \text{H}_3\text{N} - \text{H}^+ \rightarrow \text{N}_3^- \]

### Step 4: Write the Conjugate Base
After removing the H⁺ ion, we are left with the conjugate base, which is represented as N₃⁻.

### Step 5: Name the Conjugate Base
The conjugate base N₃⁻ is known as the azide ion.

### Final Answer
Thus, the conjugate base of hydrazoic acid (H₃N) is N₃⁻ (azide ion).
