Question

What solute particules are present in an aqueous solution of this compound HCOOH

Answer 1

HCOOH, H₃O⁺, and HCOO⁻

Explanation:

HCOOH is the major solute.

However, HCOOH is a weak acid. It dissociates slightly in aqueous solution.

HCOOH + H₂O ⇌ HCOO⁻ + H₃O⁺

Thus, two other solute particles are HCOO⁻ and H₃O⁺.
