Verified step by step guidance

Understand the pH scale: The pH scale ranges from 0 to 14, where a pH less than 7 indicates an acidic solution, a pH of 7 is neutral, and a pH greater than 7 indicates a basic (alkaline) solution.

Review the properties of acids: Acids are substances that donate protons (H+) in aqueous solutions. They typically have a pH less than 7.

Review the properties of bases: Bases are substances that accept protons (H+) in aqueous solutions. They typically have a pH greater than 7.

Identify the untrue statement: Compare each statement with the known properties of acids and bases. The statement 'Acids have a pH greater than 7' contradicts the definition of acids, as they should have a pH less than 7.

Conclude which statement is untrue: Based on the definitions and properties of acids and bases, the statement 'Acids have a pH greater than 7' is untrue.
