Uxcell pH8.2 to pH10 Test Strips 160 Litmus Indicator Paper Alkaline Acid Testing, 2 Pack

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,s and classroom analytical chemistry.

Advantage
There are 8 color-coded scales that go from 8.2 to 10. Also can be used to determine the strength of acid and base, as we go from 8.2 to 10 the basicity of the solution increases.

Instruction
Dipping 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. The higher the pH value, the stronger the alkalinity.

NOTE
The test strip itself is yellow. Not 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.
