THE CHEMICAL COMPOSITION OF AQUEOUS SOLUTIONS (pp. 94-98) Electrolytes – forms ions when dissolved in water (or certain other solvents) and thus produce solutions that conduct electricity. Strong electrolytes – ionize essentially completely Weak electrolytes – ionize only partially Solution of weak electrolyte will be a poorer conductor than a solution containing an equal concentration of a strong electrolyte Brønsted-Lowry theory Acid is a proton donor Base is a proton acceptor H2O + HNO2 H3O+ +
