Why is acetic acid a weaker acid than hydrochloric acid?
HCL is stronger than acetic acid because it undergoes almost complete ionisation when dissolved in water(i.e. formation of H^+ and Cl^- ion) whereas when acetic acid is dissolved in water only 5\% of it is dissociated into H^+ and CH3COOH^- ions.
Is HCl a stronger acid than acetic acid?
Hydrochloric acid is a stronger acid compared to acetic acid. The lower the pH value, the higher is the concentration of hydrogen ions (protons) in the solution.
Why concentrated acids are more dangerous than dilute acids?
Concentrated acids are acids mixed with very little water. They are much more dangerous than dilute acids. Concentrated acids are corrosive . They can attack metals and destroy skin if spilled.
Why is dilute hydrochloric acid considered a strong acid?
HCl is a strong acid because it dissociates almost completely. By contrast, a weak acid like acetic acid (CH3COOH) does not dissociate well in water – many H+ ions remain bound-up within the molecule.
How much stronger is hydrochloric acid than acetic acid?
Acid strength depends upon ease of ionization of the ‘acidic hydrogen’ forming hydronium ions by proton transfer. (Bronsted-Lowry Theory). HCl is one of the ‘strong acids’ and as such ionizes 100\% whereas Acetic Acid (HOAc <=> H + OAc) is a ‘weak acid’ and ionizes less than 100\% (~1.3\% at 25C).
Why can a weak acid be concentrated?
In fact, it’s possible to have a concentrated strong acid – but it’s also possible to have a concentrated weak acid. This is because concentration refers simply to how much of the acid is present in a given volume of water, and how much the acid ionises in water is largely irrelevant to this.
Why is dilute acetic acid stronger than highly concentrated acetic acid?
Acetic acid, on the other hand, dissociates partially (that is, about 1 out of 100 molecules separates from its hydrogen ion). In an acetic acid solution, there is a large number of undissociated CH 3 COOH molecules, and just a few H + and CH 3 COO – ions. Hence, dilute HCl acid is stronger than highly concentrated acetic acid.
Is hydrochloric acid HCl a strong or weak acid?
Explanation: Hydrochloric acid H Cl is a strong acid because it is a strong electrolyte and it is considered that will completely dissociate in water to produce a high number of ions H + and Cl−. However, acetic acid H C2H 3O2 is a weak acid and will partially dissociate in water producing a small number of ions H + and C2H 3O− 2.
What happens when hydrochloric acid dissociate?
This means if you had one mole of hydrochloric acid (HCl) molecules, they would all ‘split’ to form one mole of H+ ions and one mole of Cl– ions. Weak acids, such as ethanoic acid (CH3COOH), do not fully dissociate.
What is the difference between strong acid and weak acid?
The term “strong acid” refers to the amount of ionization strong acids are effectively 100\% ionized in solution while weak acids have a lower \% ionization as their concentration increases.
