The chemical activity (a) of an ion in the solution is related to the actual concentration of the ion. Which one, if any, of the following statements is actually true? (i.) The chemical activity of an ion is closest to the actual concentration when the ion concentration is very high. (ii.) Chemical activity and the activity coefficient are two names that have the same meaning. (iii.) A substance in its standard state will have a chemical activity of 0. (iv.) In a solution with high ionic strength in the background, Cl^-^ ions will have less repulsion for each other. (v.) Actually, none of this is true.
