I learned to separation techniques based on the chemic properties of a substance. I separated sodium chloride, benzoic acid, te dioxide, and iron.

I accomplished this by using the curious properties of each material and their differences in pee solubility. Possible observational errors accommodate non properly removing all the iron/salt/benzoic acid from sand. Residue in beaker and cups not completely translate away for accurate mass weight. Another error could start been not properly drying the benzoic acid filter paper or sand mixture before weighing. Questions: A. How did your proposed procedures or lam cha! rts at the beginning of this experiment compare to the actual procedures of this lab operation? The procedures that I listed followed closely to those of the initial flow charts. woful water saturated content proved to be truly knockout because there was often residual content remaining in the containers.
