Question

when co2 dissolves in water it chemically combines with water to form?​

Answer 1

Answer:

When CO₂ dissolves in water, it reacts with water to form a weak acid called Carbonic Acid (H₂CO₃).

Explanation:

• On dissolving carbon dioxide in water, carbonic acid is formed as some part of the dissolved Carbon dioxide reacts with water.
• Equation: CO₂(aq) + H₂O→ H₂CO₃
• The formation of Carbonic acid makes the water acidic.
• Carbonic acid is a weak acid and partially dissociates to carbonate and bicarbonate ions.
