Use strips of pH indicator
paper to find a liquid with the same pH.
It can be noticed that all curves have the same S-Shape, characteristic of the irradiation response of a pH indicator
in an acid-base titration with different sensitivities.

1% to 5% by weight of a pH indicator
that is substantially colorless at pH 7 and develops a color in an acidic environment, (b) 20% to 90% by weight of a surfactant (c) 5% to 55% by weight of a polyalkyfene glycol, (d) 0%

By encapsulating pH indicator
dyes into coatings applied to Ocean Optics' Smart pH Cuvettes, proprietary miniature fiber optic spectrometers and accessories can be used for optical pH sensing of 5.
The majority of cultivated plants can efficiently grow and fruit only in non-acid soils and therefore, soils with the pH indicator
lower than 5 have to be limed.
Delvoscan, part of the DSM Delvotest system, reveals antibiotic residues by measuring acid levels that show up as a colour change on a pH indicator
We know that sugar, salt, and pH can act as food preservatives, a nd since we already carry pH indicator
strips, all we had to find was some way of measuring solute concentrations.
A Nitrizine paper (Apothecon, Princeton, NJ) is a pH indicator
paper tape that changes from yellow to blue through a pH range of 4.
While attempting to synthesize a substance that would serve as a pH indicator
, Bottiger created a novel, brilliant red dye that did not require a mordant to stain textile fibers.
