3475views1rank - 교과서 질문Many compounds are only partially dissociated into ions in aqueous solution. Trichloroacetic acid (CCl₃CO₂H), for instance, is partially dissociated in water according to the equationCCl₃CO₂H (aq) → H⁺ (aq) + CCl₃CO₂⁻ (aq)For a solution prepared by dissolving 1.00 mol of trichloroacetic acid in 1.00 kg of water, 36.0% of the trichloroacetic acid dissociates to form H⁺ and CCl₃CO₂⁻ ions.What is the total concentration of dissolved ions and molecules in 1 kg of water?1949views
