Question
The objective of this experiment is to separate and quantify the phosphorus from a sample of commercial fertilizer. This is a multi-step process, and will require that you know the chemical compound that contains the phosphorus and the state it is in at each step of the procedure.
Step 1: Isolate the water soluble components of the fertilizer from the insoluble components.
Step 2: Chemically separate the phosphorus from the other components using MgSO4.
Despite the confusing labeling convention for fertilizers, the phosphorus in fertilizer is present in the form of a salt with the chemical formula
After step 1, the phosphorus can be found in the
Once the chemical separation of phosphorus in step 2 is accomplished, the molecular formula of the compound containing the phosphorus is
After step 2, the phosphorus can be found in the
