Litmus papers are used to determine the pH level of a liquid and determine if a solution is acidic. Widely used for industrial chemical testing, science education, laboratory use, drinking water, aquariums, and classroom analytical chemistry.SpecificationTesting Paper Size: 54mmx9mm (L*W)Overall Size: 70mmx45mmx5mm (L*W*H)Packing List: 2 x Litmus Test Kit (80/Pack,160pcs)AdvantageCan be used to determine the strength of acid and base conveniently. Sensitive to the environment and temperature changes.InstructionDipping the test paper into a solution and observing the change in color of the paper. After one second read the pH value. If the test paper turns red, the solution is acidic.NOTENot applicable for oil and acid-base solutions with a concentration of less than 0.01%. Should be stored in a dry place protected from light.

The pH of pure water is 7. Liquids with a larger concentration of hydrogen ions than water are acid and have a pH value less than 7. Liquids with a lower concentration of hydrogen ions on the other hand, are base and have a pH value higher than 7.

When encountering alkaline solution (pH>8), the red litmus paper turns blue, and when encountering acid solution (PH<4.5), the blue litmus paper turns red. When the pH value of the solution is between 4.5-8.0, the red litmus and blue litmus papers will not change color.

Litmus papers are used to determine the pH level of a liquid and determine if a solution is acidic, basic, or neutral. Widely used for industrial chemical testing, science education, laboratory use, drinking water, swimming pool, spas, aquariums, and classroom analytical chemistry.SpecificationAccuracy: 0.3 pHTesting Range: 6.9-8.4Testing Paper Size: 54mmx9mm (L*W)Overall Size: 70mmx45mmx5mm (L*W*H)Packing List: 4 x Litmus Test Kit (80/Pack,320pcs)AdvantageThere are 6 color-coded scales that go from 6.9 to 8.4. Also can be used to determine the strength of acid and base, as we go from 8.4 to 6.9 the acidity of the solution increases.InstructionDipping the pH paper into a solution and observing the change in color of the paper. After one second, compare it with the standard color cards and read the pH value.
