Question

a 2.5 m acid produces 0.035 m h⁺ in solution. is this a strong or a weak acid?
strong acid! the acid produces a significant amount of h⁺ ions in solution.
weak acid! only a small proportion of the acid dissociates to produce h⁺.
weak acid! the majority, but not all, of the acid reacts with water to produce oh⁻ and h⁺.
its not possible to determine this without the chemical formula of the acid.

Explanation:

A strong acid completely dissociates in solution. Here, a 2.5 M acid only produces 0.035 M H⁺, indicating only a small proportion of the acid has dissociated. Weak acids only partially dissociate in solution.

Answer:

B. Weak acid. Only a small proportion of the acid dissociates to produce H⁺.
