Students can test solutions for acid or base determination. Easy-to-use red litmus paper turns blue for bases and blue litmus turns red for acids. 100 strips of each. Not for measuring the pH of natural waters, such as streams, rivers and lakes. This litmus paper is bundled with chromatography paper (such as separating mixtures of colored dyes or inks). The paper is made from cotton cellulose, is .16 mm thick, has a filtration speed of 22 seconds, and an ash content of .1%.
Features
- Our litmus paper is a simple way to determine without a doubt if a solution is acidic or basic, with a second test to confirm your findings
- Laboratory grade chromatography test paper for separating mixtures into their components
- No color chart is needed to determine findings with litmus paper; these tests are designed for determining if the pH is above or below a certain level NOT giving a precise pH value
- All the papers in this bundle are QUALITATIVE, not quantitative
