pH Indicator Paper – Johnson
pH indicator paper, often branded as Johnson, is a type of test paper used to measure the pH level of a solution. The paper is coated with a pH-sensitive dye that changes color depending on the acidity or alkalinity of the solution it is immersed in.
Uses:
- Testing Acidity/Alkalinity: This paper helps determine the pH range of a liquid, which is crucial in various fields such as chemistry, biology, and environmental science.
- Educational Purposes: It’s widely used in educational settings to teach students about pH levels and chemical reactions.
- Industrial Applications: In manufacturing and quality control, pH indicator paper is used to ensure that solutions meet required pH specifications.
- Water Testing: It is employed in water quality testing to check for the presence of acids or bases.
