Strip Reaction Limit of Detection: 1000ppm; Litmus papers are used to determine the pH level of a liquid and determine if a solution is acidic
Advantage: Can be used to determine the strength of acid and base conveniently. Sensitive to the environment and temperature changes
Instruction: Dipping 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
Application: Widely used for industrial chemical testing, science education, laboratory use, drinking water, aquariums, and classroom analytical chemistry
NOTE: 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
