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.

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.
