Question: a) NaCl + H2O solutions are two-component systems (C = 2). But wait! These solutions contain 1. Na ions, 2. Cl-ions and 3. H2O molecules.

a) NaCl + H2O solutions are two-component systems (C = 2). But wait! These solutions contain 1. Na ions, 2. Cl-ions and 3. H2O molecules. Shouldn't aqueous NaCl solutions be classified as three-component systems (C = 3)? Explain. b) Liquid water contains H2O molecules together with H' and OH-ions produced by the dissociation reaction H20 = " + OH-. But liquid water is a one-component system (C = 1). Explain
