Which statement about boric acid as a neutralizer is true?

Explanation:
Acid strength describes how completely an acid donates protons in water. Boric acid is a weak acid because it only slightly dissociates in water; its dissociation constant is about 10^-9, so most of the boric acid molecules stay intact and only a tiny amount produces hydrogen ions. That means it lowers pH only modestly at a given concentration, unlike strong acids which fully dissociate and cause a large pH drop. It isn’t a base, and it isn’t a neutral salt, so those statements don’t fit. In practice, that mild acid character is why it’s described as a weak acid when used as a neutralizer.
