Why Do Indicators Change Color. Ph indicators are weak acids that exist as natural dyes and indicate the concentration of h + (\ (h_3o^+\)) ions in a solution via color change. Bases cause universal indicator to change from green toward purple. Indicators are substances whose solutions change color due to changes in ph. They are usually weak acids or bases, but their conjugate base or acid forms have different colors due to differences in their absorption spectra. The dissociation of the h + ion from the indicator itself causes the colour change of a ph. In more basic solutions where the hydronium ion concentration is less than 5.0 × 10 −9 m (ph > 8.3), it is red or pink. Water molecules (h 2 o) can interact with one another to form h 3 o + ions and oh − ions. A ph value is determined from the negative logarithm of this concentration and is used to indicate the acidic, basic, or neutral character of the substance you are testing. How does the indicator’s color change occur? Ph indicators are weak acids that exist as natural dyes and indicate the concentration of h + ( h3o+ ) ions in a solution via color change.
