The correct Answer is:
To determine the number of hydroxy groups attached to boron in borax, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Molecular Formula of Borax:** The molecular formula of borax is given as Na2B4O5(OH)4·8H2O. This indicates the presence of boron (B), oxygen (O), sodium (Na), and water (H2O) in the compound. 2. **Focus on the Hydroxy Groups:** The hydroxy group is represented as -OH. In the molecular formula, we can see that there is a specific part that indicates the presence of hydroxy groups: (OH)4. This means there are 4 hydroxy groups in borax. 3. **Count the Hydroxy Groups:** From the molecular formula, we can directly see that there are 4 hydroxy groups attached to boron in borax. 4. **Conclusion:** Therefore, the number of hydroxy groups attached to boron in borax is **4**. ### Final Answer: The number of hydroxy groups attached to boron in borax is **4**. ---
