A solution with a pH greater than 7 is considered

A solution with a pH greater than 7 is considered

• A. Less than 7
• B. Equal to 7
• C. Greater than 7
• D. Cannot be determined

Answer: (C)

Understanding pH and acidity/basicity: The pH scale shows how acidic or basic a solution is. A neutral solution has pH 7. If the pH is greater than 7, the solution is basic (alkaline) because it contains fewer hydrogen ions and more hydroxide ions than neutral water. At room temperature, higher pH means lower hydrogen ion concentration, which is the hallmark of basic solutions. For example, many cleaning or soapy solutions are basic and have pH values above 7. So, a solution with pH greater than 7 is considered basic.
