Litmus Test Paper Strips - Blue
Use these blue litmus paper strips to quickly test whether a substance is acidic. Each strip reacts when dipped into a solution, turning red to indicate acidity. If the strip stays blue, the solution is either neutral or basic. Blue litmus strips are reliable tools for teaching pH principles through observation and hands-on experimentation. The strips are ideal for chemistry classrooms, STEM labs, or environmental science activities that explore acid-base reactions. Easy to handle and read, these strips help reinforce key concepts such as chemical change, solution properties, and the scientific method.
