Understanding the pH Scale Concept Map
A pH scale concept map shows how the pH scale measures how acidic or basic a solution is. pH runs from 0 to 14, with 7 as neutral at 25 degrees Celsius. Values below 7 are acidic, and values above 7 are basic or alkaline. The scale is logarithmic, so each whole step means a tenfold change in hydrogen ion concentration.
- pH definition: negative log of hydrogen ion concentration
- Acidic range: 0 to below 7, with strong acids near 0
- Neutral point: pH 7, where hydrogen and hydroxide ions are equal
- Basic range: above 7 up to 14, with strong bases near 14
- Indicators and examples: litmus, universal indicator and common household substances
Use the map to review how each range connects to the others before an exam. Build a personalized pH scale concept map from your own notes with CogniGuide.
pH Scale Questions Answered
Common questions about the scale and about making your own map.
What does the pH scale measure?
The pH scale measures how acidic or basic a water-based solution is. It is based on the concentration of hydrogen ions. A lower pH means more hydrogen ions and a more acidic solution.
Why is pH 7 neutral?
At 25 degrees Celsius, pure water contains equal amounts of hydrogen ions and hydroxide ions. Because those amounts balance, the solution is neither acidic nor basic, and its pH is 7.
Which files can I use to make a pH map?
You can upload a PDF, Word (DOCX) or PowerPoint (PPTX) file, a text or Markdown file, or an image of your notes. You can also type the topic directly.
Is CogniGuide free to use for this?
Yes. The free plan allows 5 creations a week with no payment needed. Paid plans raise those limits.
