What is H2CO3? Important knowledge about H2CO3

1. Definition of H₂CO₃

H₂CO₃, or carbonic acid, is known as a colorless, odorless chemical compound with weak acidic properties. Its English name is Carbonic acid. H₂CO₃ is made up of 2 Hydrogen (H) atoms, 1 Carbon (C) atom, and 3 Oxygen (O) atoms, with a total atomic mass of 62.03 grams/mol. Its molecular structure takes on a zigzag shape, with a carbon atom in the center connected to an oxygen atom and two hydrogen atoms through covalent bonds.

2. Properties of H₂CO₃

2.1 Physical properties of H₂CO₃: In its natural state, H₂CO₃ is liquid, colorless, and odorless, with a distinctive sour taste, and has a pH ranging from 6.5 to 6.7.

2.2 Chemical properties of H₂CO₃: Carbonic acid has weak acidic properties and can react with metals to form carbonate salts and release hydrogen. It can also react with bases to form salts and water.

3. Common chemical equations of H₂CO₃

Example: H₂CO₃ + 2NaOH -> Na₂CO₃ + 2H₂O(Reactionwithabase)

4. Synthesis of H₂CO₃

4.1 Laboratory synthesis of H₂CO₃: H₂CO₃ can be synthesized from a reaction between CO₂ and water: CO₂ + H₂O -> H₂CO₃.

4.2 Industrial synthesis of H₂CO₃: In industry, H₂CO₃ is usually synthesized by mixing CO₂ gas with water under high pressure.
