From the Integrating Mathematical Problem Solving project by Mathematics in Education and Industry (MEI), this activity for post-16 students demonstrates that the acidity of a solution depends on the number of hydrogen ions per litre; the number of hydrogen ions per litre varies so much that a logarithmic scale is used. Topic areas covered are:
• Logarithms to base 10
• Powers of 10 and standard form
• Logarithmic scale
