Answer:
Explanation:
Carbon dioxide CO₂ is an acidic gas.
Most oxides of non-metals are acidic gases and they behave like a true acid in solution. They have all properties of an acid in this regard.
When CO₂ solution is formed, a carbonic acid is produced. This is a weak acid:
CO₂ + H₂O ⇄ H⁺ + HCO₃⁻
Answer:
The incorrect about reasoning is that there is hydrogen ion present in the solution of dissolved carbon dioxide in water.
Explanation:
The acid ph is less than 7.
If we have a solution of carbon dioxide it means we have dissolved carbon dioxide gas in water and this leads to reaction of carbon dioxide gas with water to produce carbonic acid.
[tex]CO_{2}+H_{2}O--->H_{2}CO_{3}[/tex]
This carbonic acid formed dissociates into carbonates and proton.
The formation of proton (hydronium ion) results the acidic pH of the solution.

[tex]HCO_{3}^{-}-->H^{+}+CO_{3}^{-2}[/tex]
