Mostly have an question with one.
Two and Three a relatively have an answer.
Okay, then I will provide you with an explanation for 1. This looks like the first experiment that I performed for my Quantitative Analysis course a while back. The answer should be provided in your prelab worksheet or in your Quant. book. The non-zero blank correction accounts for the residual sample left over, in this case EDTA, in the weighing boat, beaker, or weighing paper, etc. when you are adding that sample to something in your next step. You take the weighing boat, beaker, or weighing paper, etc. and reweigh it. The number that you get is your non-zero correction factor.
