Hi Tom,
As I just said to Marshall, I do believe the scales pick up on weight
differences, but due to those 'inaccuracy' factors I stated {and probly many
more?} I don't think the exercise was of any real value. Gave me something to
play around with and kept me out of mischief for a while if nothing else <g>.

Hello Neville,
I think you are seeing inaccuracies in your measurements, and/or some drift in
the scale.
I think you may need a pretty concentrated solution to measure the difference
in weight in a small sample. Keep in mind that a 1% concentration is 10000
PPM. If you were able to measure 0.001g at 5000 g total, and had a highly
concentrated sample, you may be able to see a difference in weight.

Subject: CS>Wet weight?
Could someone kindly help me out here?
I've been playing around with some small jewellers scales {0.001g up to 10g}
test weighing some EIS and found I have already observed one EIS solution that
actually weighs *less* than plain DW...???
How can this be so?
Or is this where Density or Specific Gravity of silver comes in, which I
believe is 10.5 {and this is probly SG of powdered silver as well, not the same
form of silver that we produce using electrolysis?} Or perhaps it indicates
different characteristics of ions and/or atomic ion clusters in solution.
If this is where 'mole' weight comes in then I'll just stick those scales back
in the cupboard again and won't bother going any further cos that's *well* over
my capacity of chemistry/physics understanding.
I'm aware this is a bit of a cowboy method of measuring, and probly won't be
100% accurate, but the scales DO indicate something with a couple of different
solutions I've played around with, which means they certainly appear to be good
enough for my exercise.
