The main product obtained when a solution of sodium carbonate reacts with mercuric chloride is

Options

A. `Hg(OH)_(2)`
B. `HgCO_(3).HgO`
C. `HgCO_(3)`
D. `HgCO_(3).Hg(OH)_(2)`

Explanation

To solve the problem of determining the main product obtained when a solution of sodium carbonate reacts with mercuric chloride, we can follow these steps:

### Step 1: Write the Chemical Equations
First, we need to identify the reactants and write the balanced chemical equation for the reaction. The reactants are sodium carbonate (Na2CO3) and mercuric chloride (HgCl2).

**Chemical Equation:**
\[ \text{Na}_2\text{CO}_3 + \text{HgCl}_2 \rightarrow \text{HgO} + \text{NaCl} + \text{CO}_2 \]

### Step 2: Identify the Products
From the balanced equation, we can see that the products formed are:
- Mercuric oxide (HgO)
- Sodium chloride (NaCl)
- Carbon dioxide (CO2)

### Step 3: Analyze the Products
Among the products formed, we need to identify the main product. In this case, mercuric oxide (HgO) is the primary solid product formed in the reaction, while sodium chloride and carbon dioxide are also produced.

### Step 4: Check the Options
Now, we can check the provided options to see which one corresponds to the main product formed:
1. HgOHCl2
2. HgCO3 and HgO
3. HgCO3
4. HgCO3 and HgOHCl2

The correct answer based on our analysis is:
- **Option 2: HgCO3 and HgO** (since HgO is the main product formed)

### Final Answer
The main product obtained when a solution of sodium carbonate reacts with mercuric chloride is **HgO (mercuric oxide)**.
