The conjugate acid of azide ion is

Options

A. `NH_(3)`
B. `N_(3)H`
C. `N_(3)H`
D. `Na_(2)^(-)`

Explanation

To find the conjugate acid of the azide ion (N₃⁻), we can follow these steps:

### Step 1: Identify the Azide Ion
The azide ion is represented as N₃⁻. It carries a negative charge.

### Step 2: Understand Conjugate Acids and Bases
A conjugate acid is formed when a base gains a proton (H⁺). In this case, since the azide ion is a base (due to its negative charge), we can convert it to its conjugate acid by adding a proton.

### Step 3: Add a Proton (H⁺) to the Azide Ion
To find the conjugate acid, we add H⁺ to the azide ion:
- N₃⁻ + H⁺ → N₃H

### Step 4: Write the Result
The result of this addition gives us the conjugate acid of the azide ion, which is N₃H.

### Final Answer
The conjugate acid of the azide ion (N₃⁻) is N₃H.
