Boric acid is primarily soluble in water.
Based on the provided reference, "Boric acid and borate salts are soluble in water." This indicates that water is a primary solvent for boric acid. The reference further notes that most boron in aqueous solution will exist as boric acid or borate ion, reinforcing its solubility in water.
While water is the most common and significant solvent for boric acid, its solubility is also influenced by temperature. Solubility generally increases as the temperature of the water rises.
Here's a brief look at boric acid solubility:
- Primary Solvent: Water
- Influence: Temperature significantly affects solubility.
Solubility of Boric Acid in Water (Example Data - General Trend):
| Temperature (°C) | Solubility (g/100 mL water) |
|---|---|
| 0 | ~2.5 |
| 25 | ~5.5 |
| 100 | ~27.5 |
Note: These values are approximate and can vary slightly depending on the source.
Understanding boric acid's solubility in water is crucial for its various applications, from chemical synthesis to its use as an antiseptic or insecticide, as it is typically used or encountered in aqueous solutions. The reference confirms this, stating that in aqueous solutions, boron predominantly exists as boric acid or the borate ion.
