Question
Analyze these statements about a buffer solution:
(I) A buffer solution stabilizes pH levels when small amounts of acids or bases are introduced. (II) The pH of a neutral salt solution is consistently 7. (III) Acetic acid (CH₃COOH) is categorized as a strong acid, completely dissociating in water.Solution
Only statement (I) is correct; a buffer solution indeed stabilizes pH against minor additions of acid or base. Statement (II) is incorrect as the pH of a salt solution can vary based on the acid and base from which it is derived. Statement (III) is also incorrect, as acetic acid is a weak acid that does not fully dissociate in water.
