Verified step by step guidance1
Step 1: Understand the concept of pH scale. The pH scale ranges from 0 to 14, where 7 is neutral. Acids have a pH less than 7, and bases have a pH greater than 7.
Step 2: Review the definition of acids. Acids are substances that donate protons (H⁺ ions) in a chemical reaction. This is known as the Brønsted-Lowry definition of acids.
Step 3: Review the definition of bases. Bases are substances that accept protons (H⁺ ions) in a chemical reaction, according to the Brønsted-Lowry definition.
Step 4: Analyze the given statements. Compare each statement with the definitions and properties of acids and bases.
Step 5: Identify the incorrect statement. Based on the pH scale, acids cannot have a pH greater than 7, so the statement 'Acids have a pH greater than 7' is not true.
