Sodium chloride solution is neutral. What does that say about its ions?

1. Neutral is defined by comparing the two ion concentrations, not by their absence. 2. A neutral solution has equal concentrations of hydronium and hydroxide ions. 3. Both ions are still present, because water itself supplies them. 4. An excess either way would make the solution acidic or basic instead. _Source: OpenStax Chemistry (CC BY 4.0), Ch 14 "Acid-Base Equilibria", section 14.2 pH and pOH_
