Litmus Paper: A Guide to Use and Properties

What is litmus paper?

Litmus paper is a material commonly used to measure the pH of a solution. It is a strip of paper soaked in chemicals that change colour based on the acidity or alkalinity of the liquid it comes into contact with. Its use is not limited to scientific laboratories, but it also finds a place in the kitchen and in the wellness sector.

How to use litmus paper?

Using litmus paper is a simple and quick operation. Here’s how to proceed:

1. Prepare the sample: Take the liquid you wish to test (water, juice, etc.).
2. Dip the paper: Insert the strip of litmus paper into the liquid for a few seconds.
3. Observe the colour change: Remove the paper and compare the colour obtained with the reference scale provided with the product.

Practical uses of litmus paper

Litmus paper can be used in various contexts:

• In the kitchen: To check the pH of preserves, jams or sauces, ensuring that the acidity level is correct.
