Write down the physical and chemical properties of h2so4
Answers
Physical properties: H2SO4 is a colorless or slightly yellow viscous liquid with a pungent odor. It has a density of 1.84 g/mL, boiling point of 337 °C, and melting point of 10 °C. "Concentrated" sulfuric acid is 98% in water, and is the most stable form.
Chemical properties Sulfuric acid is a very strong, diprotic acid. It is hygroscopic and readily absorbs moisture from air. It is a powerful oxidizing agent and reacts with many metals at high temperatures. Concentrated H2SO4 is also a strong dehydrating agent. Addition of water to concentrated sulfuric acid is a very exothermic reaction and can lead to explosions.
Answer:
