Question

which of these terms describes hf? weak acid weak base strong acid strong base

Explanation:

HF (hydrofluoric acid) is a weak acid. In water, it does not completely dissociate into ions. Strong acids like HCl, H₂SO₄, HNO₃ dissociate completely. Bases are substances that donate OH⁻ ions or accept H⁺ ions. HF is an acid (donates H⁺ ions) not a base. Since it does not fully ionize, it is a weak acid.

Answer:

weak acid
