Review on Versatile Litmus Strips π¬ for All Applications: Universal Application Paper by Pavel Craig
Ideal for educational purposes
Ideal for basic science/chemistry labs. They're affordable too. I am a high school science teacher and also homeschool with my eldest son (due to an autoimmune disease). He used them for a chemistry problem and they did exactly what they were supposed to. If your strips show no significant changes, it is most likely due to similar/low pH levels. Try many more acidic substances and mixtures (vinegar/OJ/etc) and you will see the difference.
- Used for routine testing and educational experiments only.
