Description
Accuracy: 1 pH; litmus papers are used to determine the pH of a liquid and determine if a solution is acidic, alkaline, or neutral
Advantage:100 pre-cut long strips are well sealed with 1 single plastic packaging sleeve to avoid damage, convenient to use. Highly sensitive to environmental and temperature changes
Instructions: Dip the pH paper into a solution and observe the color change of the paper. After one second, compare with the standard colour cards and read the pH value. The smaller the pH, the stronger the acid, the higher the pH value, the stronger the alkalinity, at a pH of 7, the solution is neutral
Application Widely used for industrial chemical testing, science education, laboratory purposes, drinking water, aquariums and analytical chemistry in classroom
NOTE: Does not apply to oil and acid-base solutions with a concentration of less than 0.01%. Should be stored dry and protected from light
