An unknown liquid was found in a science room and was analyzed by some Chemistry 20 students. To determine its possible identity, they attempted first to determine the pH using various indicators. The results of these tests were as follows: phenolphthalein stayed colourless • bromothymol blue turned yellow • methyl orange turned red • methyl violet stayed blue phenolphthalein stayed colourless Based on the results, what is the possible pH range of the unknown liquid? Show your work that leads you to determine the pH range.
