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.
