SO3 - the highest sulfur oxide, chemical bond type: covalent polar chemical bond. Under normal conditions, volatile, colorless liquid with a suffocating odor. At temperatures below 16.9 C, it solidifies to form a mixture of various crystalline modifications of solid SO3. When SO3 interacts with water, caustic sulfuric acid is formed.
