Litmus papers are used to determine the pH level of a liquid and determine if a solution is acidic(Red), basic(Blue), or neutral. Widely used for industrial chemical testing, science education, laboratory use, drinking water, swimming pool, spas, aquariums,s and classroom analytical chemistry.SpecificationAccuracy: 1 pHTesting Range: 1-14Testing Paper Size: 50mmx9mm (L*W)Overall Size: 72mmx49mm (L*W)Packing List: 1 x Litmus Test Kit (80/Pack)AdvantageThere are 14 color-coded scales that go from 1(being the most acidic) to 14(being the most alkaline). Also can be used to determine the strength of acid and base, as we go from 7 to 1 the acidity of the solution increases. Comes in a box, easy to store and reduces the chance of moisture.InstructionDipping the pH paper into a solution and observing the change in color of the paper.

NOTE:This paper does not apply to buffer solutions and very weak acid-base solution concentration lower than 0.01%.Please note that solutions with a pH of 5.5 will result in a yellow colored test strip that resembles the original color of the dry strip.Store in a cool, dry place away from sunlight. Instructions: 1. Take one strip and dip it into the solution you would like to measure. The color of your strip will change immediately.2. Quickly match this color against the color chart on the inside of package to obtain the pH in 15 seconds. Do not wait or let the strip dry!3. The number next to the color on the chart is your pH. The pH scale ranges from 1 (very acidic) to 14 (very basic), 7 is neutral. Description:Testing Range: 1-14Overall Size: 55x9mm / 2x0.
