Paper Universal pH

Precision pH Test Paper for school, colleges and universities use. Supplied in box of 10 books each with 20 strips in each container or 100 pages in a cardboard box.

A pH test strip is a strip of litmus paper with which you can measure the pH value of a liquid. The substance in the paper causes the paper to show a different colour at different acidities. This is determined by dipping part of the paper into a solution of interest and watching the color change. The packages that pH paper comes in often includes a color-coded scale indicating the pH that something has when the paper turns a certain color. For instance, if the paper turns a dark greenish-blue, the pH may likely be around 11 to 14.
