pH indicating dyes
They are used in indicator strips that reveal the acidity or alkalinity of a solution.
These substances are dyes applied at low pH, generally on wool.
With a pH meter or pH paper. Other indicator dyes (e.g. litmus, phenolphthalein) may be used if it is not necessary to determine the exact numerical pH value.

Phenolphthalein is a sensitive pH indicatorwith the formula C20H14O4
Many soluble dyes change their color with changes in pH (a measure of the concentration of acid in a solution). Such dyes may be used to indicate when the acid (base) in a solution has been neutralized by addition of an equal amount of base (acid). Each indicator dye has a particular range of pH for which it is useful. pH test strips and papers often incorporate two or more dyes to extend the range of pH over which they can be used. The best indicator dyes are strongly colored (so that only small amounts are needed), undergo an easily seen change with pH (either from one color to another, or from clear to colored), are nontoxic, and are chemically stable.
Yes.
Tomato plants are sensitive to the pH levels in the garden soil. The optimum levels should be between 6-6.8
