The Blue Litmus test paper does not come with a color chart as it cannot provide you with a defined pH value. The test strip will turn red if dipped into an acidic solution (pH <7). It will remain unchanged in an alkaline solution. Although there is no color chart, the strip will turn various shades of red, getting darker the more acidic the solution. We have tested the blue litmus with multiple pH buffers. The blue paper is blue at pH 8. At pH 7, the sample is maybe just a little red. The real change to red seems to start with pH 6.5 and lower. Using pH test paper provides a quick visual indication of the degree of acidity or alkalinity present in whatever solution is being tested. This is a vital tool for classroom projects or field trips. Our test papers offer a wide variety of pH papers. They are supplied in a clear plastic vial Instructions: Remove one Blue Litmus test paper from the vial, being careful not to touch the strip anywhere other than where you grasp it.Dip the strip into the solution to be tested for 1-2 seconds and remove.The test strip will turn red in seconds if dipped into a solution that is acidic, and will remain unchanged if not.
