What are the solute particles present in aqueous solutions of each compound? (Select all that apply.) acetic acid
Pure acetic (also called ethanoic) acid is a liquid at room temperature, so is unlikely to be in the form of particles.
In a true aqueous solution, there should be no solute particles.
Are there other parts of this question? It doesn't make sense to me.
Acetic acid is a weak acid. It ionizes about 1.3% or so. You will have a FEW H^+, a FEW acetate (C2H3O2^-) ions, but most will be in the un-ionized form of HC2H3O2 (molecular acetic acid).
Now I understand your question. Your "particles" are ions and molecules, as DrBob222 has explained.
