Answer the following question to test your understanding of the preceding section: A concentrated solution of this strong electrolyte has a lower vapor pressure than that of pure water at the same temperature. Drinks with electrolytes have salts (sodium and potassium) that help maintain ion levels for athletes that lose ions through sweat. Acetic acid, CH3COOH is a weak electrolyte because it is a weak acid. But at such a high dilution, the conductivity would be so minute that it would be masked by that of water itself (that is, by the H+ and OH ions in equilibrium with the massive 55.6 M L1 concentration of water) making values of in this region virtually unmeasurable. The nonelectrolytes are out of the discussion here as their aqueous solution would not conduct current due to the lack of charged species. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). Substances that give ions when dissolved in water are called electrolytes. The greater the strength of the electrolyte, the higher will be the conductivity. The light will glow dimly for each solution since each is a weak electrolyte.
