Why dilute hcl acid is stronger than highly concentrated acetic acid?
Answers
HCl acid ionises completely to H+ and Cl- ions (that is, about 100 out of 100 molecules donate their hydrogen ion). Hence, it is a strong acid. ... Hence, dilute HCl acid is stronger than highly concentrated acetic acid.
Explanation:
Both HCl and CH3COOH are monobasic acids. An acid is a substance that, on dissolving in water, produces Hydronium ions (H3O+). Since HCl dissociates completely in water, it is a stronger acid than CH3COOH which dissociates only partially. How?
Well, CH3COOH has 4 Hydrogen atoms but forms only 1 Hydronium ion whereas, HCl has only 1 Hydrogen atom and it dissolves in water to form one Hydronium ion, therefore it dissociates completely, i.e. gives away all of its Hydrogen atom unlike CH3COOH which donates only 1 of 4 Hydrogen atoms.
I hope I was able to clear your doubt! :D
