WebJul 16, 2024 · The pH range of 3.1 – 4.4 is the color-change interval of methyl orange, the range of pH values over which the color change takes place. There are many different acid-base indicators. Their color changes have a wide range of pH values (Figure 3). WebWhy is phenolphthalein a better indicator than methyl? If you use phenolphthalein, you would titrate until it just becomes colourless (at pH 8.3) because that is as close as you can get to the equivalence point. On the other hand, using methyl orange, you would titrate until there is the very first trace of orange in the solution. …
