Best Answer

The strength of the acid depends on the amount of hydrogen ions which come from the dissociation of the acid. Hydrochloric acid (HCl) splits entirely into ions: H+ and Cl-, due to a large acid dissociation constant (Ka). Ka of an acetic acid is relatively small (10-4.8). That means that lots of molecules stays undissociated and do not produce H+ ions.

Why is spilling 1 M acetic acid relatively harmless compared to spilling 1 M hydrochloric acid?

Acetic acid is much weaker than hydrochloric acid. Weak acids do not fully dissociate into their contituent ions, so there will be a smaller concentration of H+ ions in 1 M acetic acid than in 1 M hydrochloric acid (even though the concentrations of the two acids are the same). It's the H+ ions that burn your skin - that do the damge. So, a small concentration of H+ ions, which is what we have in 1 M acetic acid, will therefore be pretty safe.


Why benzoic acid is comaritively weaker acid than acetic acid?

Why acetic acid is weaker than iodoacetic acid?

Yes. due to the presence of electron withdrawing iodo group, iodoacetic acid will be stronger than acetic acid.


Is ethanoic acid stronger than hydrochloric acid?

No it isn't. Ethanoic acid, more commonly called acetic acid, is a weak acid. Hydrochloric acid is a strong acid.


Why is a 10 percent solution of hydrochloric acid stronger than a 10 percent solution of acetic acid?

Acetic Acid is a weak acid in that it is only partially dissociated. Hydrocholric acid is highly corrosive and is much stronger
