Which statement represents the characteristics of a basic solution on the pH scale?

• A. pH less than 7
• B. pH equal to 7
• C. pH greater than 7
• D. pH equal to 0

Answer: (C)

A basic solution is characterized by a pH greater than 7. On the pH scale, which ranges from 0 to 14, values lower than 7 indicate acidity, while a pH of exactly 7 represents a neutral solution, such as pure water. As the pH increases above 7, the solution becomes increasingly basic (or alkaline), reflecting a higher concentration of hydroxide ions relative to hydrogen ions. Therefore, when identifying characteristics of a basic solution, it is essential to recognize that anything above a pH of 7 indicates a decrease in acidity and an increase in basicity. This aligns perfectly with the definition and properties of acids, neutrals, and bases on the pH scale.
