Give the Reaction of `SO_2` with mineral colemanite ( `Ca_2B_6O_11`)

Answer

To solve the problem of the reaction between sulfur dioxide (SO₂) and mineral colemanite (Ca₂B₆O₁₁), we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants in this reaction are colemanite (Ca₂B₆O₁₁) and sulfur dioxide (SO₂).

2. **Consider the Reaction Conditions**:
- The reaction is assumed to occur in the presence of water (H₂O).

3. **Write the Reaction**:
- When colemanite reacts with sulfur dioxide in the presence of water, it produces boric acid (H₃BO₃) and calcium sulfite (CaSO₃).
- The unbalanced reaction can be written as:
\[ \text{Ca}_2\text{B}_6\text{O}_{11} + \text{SO}_2 + \text{H}_2\text{O} \rightarrow \text{H}_3\text{BO}_3 + \text{CaSO}_3 \]

4. **Balance the Reaction**:
- To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. The balanced equation is:
\[ 2 \text{Ca}_2\text{B}_6\text{O}_{11} + 2 \text{SO}_2 + 9 \text{H}_2\text{O} \rightarrow 6 \text{H}_3\text{BO}_3 + 2 \text{CaSO}_3 \]

5. **Final Products**:
- The final products of the reaction are boric acid (H₃BO₃) and calcium sulfite (CaSO₃).

### Final Balanced Reaction:
\[ 2 \text{Ca}_2\text{B}_6\text{O}_{11} + 2 \text{SO}_2 + 9 \text{H}_2\text{O} \rightarrow 6 \text{H}_3\text{BO}_3 + 2 \text{CaSO}_3 \]
