Universal Indicator Because indicators change colors over different pH ranges, they may sometimes be combined to offer color changes over a wider pH range. For example, "universal indicator" contains thymol blue, methyl red, bromothymol blue, thymol blue, and phenolphthalein. It covers a pH range...
