Neutral Litmus Paper [Vial of 100 Test Strips] for Acidity/Alkalinity Testing

Description Neutral Litmus test paper is utilized to determine whether a solution is neutral or has acidity/alkalinity. The test strip will turn red if dipped into an acidic solution (pH <7) or blue if dipped into an alkaline solution (pH >7). Perfect for science experiments and when a precise value is not needed. The Neutral Litmus test paper does not have a color chart as it cannot provide a defined pH value, but it will let you know if you are handling an acidic or basic solution. Instructions: Remove one Neutral 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 an acidic solution or blue if dipped into an alkaline solution. NOTE: The solution must be water-based.
