Reaction of CH3COOH & CH3CH2OH gain chemical equilibrium in open pot but CaCo3 do not gain chemical equilibrium in open pot, Why ?

Question

Answer

When CH3COOH (acetic acid) is dissolved in water, it ionizes and reacts as a weak acid. It donates a proton (H+) to water, forming the acetate ion (CH3COO-) and the hydronium ion (H3O+).

The reaction can be represented as follows:

CH3COOH + H2O ⇌ CH3COO- + H3O+

This reaction is reversible, meaning that the acetate ion can also react with the hydronium ion to regenerate acetic acid and water:

CH3COO- + H3O+ ⇌ CH3COOH + H2O

Overall, acetic acid is a weak acid, which means that it only partially ionizes in water and exists mostly in molecular form.

Answer

CaCO3 is ionic. so, it undergoes complete dissociation and does not attain equilibrium as the backward reaction doesn't take place. CH3COOH and C2H5OH dissociate incompletely so, they can attain equilibrium as backward reaction is also possible.
