The pH range of a base is typically above 7. A solution with a pH of 7 is considered neutral, which is the pH of pure water at 25°C (77°F). As the pH increases, the solution becomes more basic or alkaline. Generally, a pH range of about 7.1 to 14 is considered to indicate the presence of a base, with stronger bases having higher pH values closer to 14.
