WebSome of the water molecules lose a hydrogen and become hydroxide ions (OH −). The "lost" hydrogen ions join up with water molecules to form hydronium ions (H 3 O +). For simplicity, hydronium ions are referred to as hydrogen ions H +. In pure water, there are an equal number of hydrogen ions and hydroxide ions. The solution is neither acidic ... WebThe pH Level Rises. When you add pure water to an acidic solution, the solution becomes less acidic and the pH goes up -- to a point. For example, if you add pure water to a relatively acidic solution that has a pH of 3.5, the pH level might go up to a 4 or 5. You cannot, though, turn an acidic solution into a base solution or make it neutral ...
