Options

A. For coloured ppt./Black ppt
B. For coloured solution.
C. for clear/colourless solution
D. For white ppt.

Answer

To solve the given reaction step by step, let's break down the components and analyze the reaction:

### Step 1: Identify the Reactants
The reactants in the reaction are:
- **BaSO₃** (Barium Sulfite)
- **SO₂** (Sulfur Dioxide)
- **H₂O** (Water)

### Step 2: Understand the Reaction Process
Barium sulfite (BaSO₃) reacts with sulfur dioxide (SO₂) and water (H₂O). This reaction leads to the formation of barium hydrogen sulfite (Ba(HSO₃)₂).

### Step 3: Write the Reaction
The balanced chemical equation for the reaction can be written as:
\[ \text{BaSO}_3 + \text{SO}_2 + \text{H}_2\text{O} \rightarrow \text{Ba(HSO}_3\text{)}_2 \]

### Step 4: Analyze the Products
The product formed is barium hydrogen sulfite, which is represented as Ba(HSO₃)₂. This compound is known to be soluble in water and typically forms a clear solution.

### Step 5: Determine the Physical State of the Products
Since Ba(HSO₃)₂ is soluble in water, it will not form a precipitate. Instead, it will yield a clear, colorless solution.

### Step 6: Evaluate the Options
Now, we need to evaluate the given options based on the reaction:
1. **Colored precipitate or black precipitate** - Incorrect, as no precipitate is formed.
2. **Colored solution** - Incorrect, as the solution is colorless.
3. **Clear colorless solution** - Correct, as the product is a clear, colorless solution.
4. **White precipitate** - Incorrect, as no precipitate is formed.

### Conclusion
The correct answer is that the reaction produces a **clear colorless solution** of barium hydrogen sulfite.
