How would you characterize a solution with a pH greater than 7?

• A. Neutral
• B. Acidic
• C. Basic
• D. Aqueous

Answer: (C)

A solution with a pH greater than 7 is characterized as basic or alkaline. The pH scale ranges from 0 to 14, where values below 7 indicate acidity, a value of 7 is neutral, and values above 7 indicate basicity. Basic solutions have a lower concentration of hydrogen ions (H+) than hydroxide ions (OH-), which contributes to their elevated pH. Common examples of basic substances include sodium hydroxide and ammonia. This understanding of the pH scale and the properties of basic solutions is essential in various scientific applications, including chemistry and biology, where the pH levels can significantly affect reactions and biological processes.
