That someone would be me. Sorry Dave, but you might want to go back and
review that exercise. I claim that both of my statements above are true,
and easily proved. Remember, the measurement in question here is Total
Dissolved SOLIDS. Are you really going to claim that *only* solids can
produce measurable conductivity when dissolved in water?! I hope not.
I won't plague the list unless there is interest, but it's quite easy to
sketch out an experiment which will demonstrate high-conductivity in the
presence of near-zero TDS.
