Question
Indicate whether each of the following experimental difficulties will lead to an artificially high or an artificially low value in the mass of phosphorus recovered.
The MgSO4 solution causes additional water soluble components in the fertilizer to precipitate out of solution.
Fertilizer companies often overformulate their fertilizers so that the nutrient content is higher than what is promised on the label.
The pH of the mixture of MgSO4 solution and fertilizer filtrate is less than 9.
The precipitate is not completely dry before it is weighed out.
Your group's procedure does not completely separate the water soluble from the water insoluble components of the fertilizer.
