¤¤Helloo¤¤
¤¤ Formula of acetic acid is CH3COOH.
¤¤ there are 4 hydrogen in the structure, but CH3 protons do not contribute to the acidity.
¤¤These hydrogens cannot be lost. There is no relation between the number of hydrogens and acidity. It is COOH hydrogen which makes it acidic.

Hey there,
CH₃COOH when added to water, ionize into-->
CH₃COOH⇄CH₃COO⁻ + H⁺
ᵃ You will see that the the ion CH₃COO does not break and does not increase the concentration of H⁺ ions.
And since,
pH=-log[H⁺]
where [H⁺]=concentration of H⁺ ions,
Hence it is a weak acid.
ᵃ Since CH₃COOH is an organic acid, hence its acidity is weak. You might be wondering how to figure out whether an acid is organic or not.
ITS SIMPLE!!! If an acid has C atom then it will be organic acid like HCOOH, CH₃COOH and H₂CO₃. Examples of inorganic acids are HCl, H₂SO₄ and HNO₃.
ᵃ H atoms will only add to acidity if they ionize and give up H⁺ ion.
ᵃ The acidity of an acid depends on its power of dissociation. Since CH₃COOH has less dissociation power, hence it is a weak acid.
