pH papers and indicators are used to determine whether a test solution is acidic or basic. The Wide Range pH Indicator Kit provides a distinct color for each separate pH reading, in a range of 1 to 14, 1 being most acidic, 7 neutral, and 14 most basic. The kit contains 2oz of liquid wide range indicator in a plastic dropping bottle. The indicator is added in a ratio of one drop of indicator to 10 drops of test solution; a 1:10 volumetric ratio. Included as well in the kit are 2 white plastic spot plates with 12 cavities each and 2 eye droppers for the test solutions as well as a color comparison card. An essential kit for teachers and students alike.
