The name of the compound `(NH_4)_2SO_4` is

Options

A. ammonium sulphate
B. ammonium sulphide
C. ammonium sulphite
D. ammonia sulphate.

Answer

To determine the name of the compound \((NH_4)_2SO_4\), we can follow these steps:

### Step 1: Identify the components of the compound
The compound \((NH_4)_2SO_4\) consists of two different parts: the ammonium ion \((NH_4^+)\) and the sulfate ion \((SO_4^{2-})\).

### Step 2: Determine the charge of the ions
- The ammonium ion \((NH_4^+)\) has a positive charge.
- The sulfate ion \((SO_4^{2-})\) has a negative charge.

### Step 3: Count the number of ions
In the formula \((NH_4)_2SO_4\):
- There are 2 ammonium ions \((NH_4^+)\).
- There is 1 sulfate ion \((SO_4^{2-})\).

### Step 4: Combine the names of the ions
- The name of the ammonium ion \((NH_4^+)\) is "ammonium."
- The name of the sulfate ion \((SO_4^{2-})\) is "sulfate."

### Step 5: Formulate the name of the compound
By combining the names of the ions, we get:
- The name of the compound \((NH_4)_2SO_4\) is "ammonium sulfate."

### Final Answer:
The name of the compound \((NH_4)_2SO_4\) is **Ammonium Sulfate**.
