Web5 jun. 2024 · Stated differently, less energy is released from making acetate ion from acetic acid than from making chloride ion from hydrochloric acid (or water from hydronium ion). Despite the lesser tendency of acetic acid to ionize, the overall stoichiometry of the two reactions is the same--as pointed out in a comment by the OP. Share Improve this answer Webas the ionisation relies on the evaporation of ions from the surface of a droplets. The detergent therefore suppresses the evaporation of other ions. Surfactants are only used …
