Re: pH meter calibration
NO, NO, NO!
One can't even *measure* the pH of distilled water, (because of too high
impedance). That is one CAN measure it, but the result is meaningless!
You have to use buffers, preferably phosphate buffers, to calibrate an
pH electrode. Some organic buffers can poison inexpensive pH electrodes,
so are best avoided.
