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.
To determine the solute particles present in an aqueous solution of acetic acid, we need to consider whether it dissociates or remains as molecules when dissolved in water.
Acetic acid, with the chemical formula CH3COOH, is a weak acid. When dissolved in water, it undergoes partial dissociation. It donates a proton (H+) to water, forming hydronium ions (H3O+) and acetate ions (CH3COO-).
So, the solute particles present in an aqueous solution of acetic acid are hydronium ions (H3O+) and acetate ions (CH3COO-).
Therefore, the correct answer is:
- Hydronium ions (H3O+)
- Acetate ions (CH3COO-)
