Answer:
A chemical indicator in solution consists of a weak acid and its conjugate base.
Explanation:
Indicators are chemicals whose solutions change color as the pH of the surrounding environment changes. They are normally weak acids or bases, but due to changes in their absorption spectra, their conjugate base or acid forms have different colors.
Plants are used to extract a variety of indicators. When the pH is varied, red cabbage juice and tea pigments, for example, show different colors. In a basic solution, the color of tea darkens, but when lemon juice is added, the color lightens. In a basic solution, red cabbage juice turns blue, while in an acidic solution, it retains its red hue.
