Low pH liquid for testing?
I'd like to test the low end sensitivity of my pH probe/meter. What low pH liquids (say, something available around my house) could I safely dip the probe into? Also, if you know the pH of the liquid you recommend, that would help, too.
Yes, I could order the low pH calibration fluid, but I figured I'd try to test at home first. It doesn't need to be exact -- just something that is lower than, say, 6.6.
