    The highly diluted HCl solution has pH 6.98. This value is at least below pH 7 (which we also expect from an acid). 2. Exact Solution (Theory) Let's abbreviate the total HCl concentration by C T = 108 M. The aqueous system consists of three components: [H +], [OH], and [Cl]. Thus, we need three equations: (1.1) strong acid (completely dissociated): [Cl] = C T (1.2) charge balance: [H
