How Do Indicators Work. This page assumes that you know about ph curves for all the. Universal indicator is the indicator. 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. Chemical indicator, any substance that gives a visible sign, usually by a color change, of the presence or absence of a threshold concentration of a chemical species, such as an acid or an alkali in a solution. Indicators are substances that change colour when they are added to acidic or alkaline solutions. The indicator changes color when it reaches a critical range of values. 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.
