At what range of the pH scale would bases typically fall?

• A. 0-6.9
• B. 7-8.0
• C. 7.1-14
• D. 6.0-7.0

Answer: (C)

Bases are substances that, when dissolved in water, increase the concentration of hydroxide ions (OH-) and decrease the concentration of hydrogen ions (H+). The pH scale ranges from 0 to 14, where a pH of 7 is considered neutral. A pH below 7 indicates acidity, while a pH above 7 indicates the presence of a base. Typically, bases have a pH range from just above 7 up to 14. This range indicates increasing alkalinity, with values closer to 14 representing stronger bases. Therefore, the option reflecting a pH range of 7.1 to 14 accurately describes where bases usually fall on the pH scale, illustrating their characteristic properties in relation to acidity and neutrality.
