You are cleaning up a lab when you see a beaker of a clear substance that is unlabeled. Your teacher tells you that if you can figure out what is in the beaker she’ll give you some bonus points (WHOOHOO) so you get right to work and start by testing the pH. You first test, with pH paper ranging from 0-14 turns up a bright yellow color. You think you could get some more information so you decide to use the litmus paper that ranges from 4.5 - 7.5. When dipped into the sample, the paper turns up a very very dark purple - almost black. You’ve seen these results before - you know what’s in the mystery beaker! Is the substance in the beaker? acidic or alkaline
