Answer 2

Weak Electrolytes Among the Given Acids:

Among the given acids, the weak electrolytes are HF, H2SO3, HNO2, and H3PO4.

The strength of an acid as an electrolyte is determined by its ability to dissociate into ions in solution. Weak electrolytes partially dissociate into ions in solution.

HF: - Hydrofluoric acid (HF) is a weak acid and a weak electrolyte. - It partially dissociates into ions in solution. - Source: H2SO3: - Sulfurous acid (H2SO3) is a weak acid and a weak electrolyte. - It also partially dissociates into ions in solution. - Source: HNO2: - Nitrous acid (HNO2) is a weak acid and a weak electrolyte. - It exhibits partial dissociation in solution. - Source: H3PO4: - Phosphoric acid (H3PO4) is a weak acid and a weak electrolyte. - It partially dissociates into ions in solution. - Source:

Identifying the Weakest Acid:

Among the given acids, HF (hydrofluoric acid) is the weakest acid. It is known for its relatively weak acidic properties compared to the other acids listed.
