Litmus Paper vs. PH Paper — What's the Difference?
By Tayyaba Rehman — Published on October 24, 2023
Litmus Paper indicates if a solution is acidic or basic, turning red or blue, respectively. PH Paper provides a specific pH value, showing a color spectrum from acidic to basic.

Key Differences
Litmus Paper: Derived from lichens, Litmus Paper is a simple tool that determines whether a solution is an acid or a base. When a substance is acidic, Litmus Paper turns red. Conversely, basic (or alkaline) substances turn the paper blue. PH Paper, on the other hand, offers a more comprehensive and quantitative measurement of a solution's pH.
PH Paper: Unlike Litmus Paper which generally offers binary results (acidic or basic), PH Paper can provide a specific pH value of a solution. This is done by matching the color that the paper turns to a pH color scale. This allows for a more nuanced understanding of a solution's acidity or alkalinity compared to the straightforward results given by Litmus Paper.
Range and Usage: Litmus Paper has a narrower focus, primarily distinguishing between acids and bases. PH Paper, however, covers the entire pH scale from 0 to 14, thus providing a specific pH reading. While both can be used in labs and for educational purposes, PH Paper's detailed results make it preferable in precise scientific applications.
Accuracy: Although Litmus Paper can quickly identify the general nature of a solution, its results are qualitative. In contrast, PH Paper offers a quantitative measurement, enabling more accuracy and specificity in determining the pH of a solution.
Application in Everyday Life: Both Litmus Paper and PH Paper find uses outside professional labs. For instance, gardeners might use Litmus Paper to check soil acidity, while aquarium enthusiasts might employ PH Paper to ensure optimal water conditions for their fish.

Are Litmus Paper results quantitative or qualitative?
Litmus Paper provides qualitative results, indicating if a solution is acidic or basic.
What's the primary use of Litmus Paper?
Litmus Paper is used to determine if a solution is acidic (turns red) or basic (turns blue).
What's the origin of Litmus Paper's color-changing ability?
Litmus Paper is made from natural dyes derived from lichens.
In what scenarios is PH Paper preferable over Litmus Paper?
PH Paper is preferable when a specific pH reading or more detailed analysis of a solution's acidity or alkalinity is needed.
Why might someone use Litmus Paper over PH Paper?
Litmus Paper is simpler to use and is suitable for basic experiments where only a general indication of acidity or basicity is needed.
Can I use PH Paper to test the pH of my pool?
Yes, PH Paper can be used to test the pH of pool water to ensure it's safe and comfortable for swimmers.
Is it possible to get a pH reading of 7.5 using Litmus Paper?
