Theory and Practice of Precipitation Gravimetry: Representative Method

Representative Method 

The best way to appreciate the importance of the theoreti- cal and practical details discussed in the previous section is to carefully examine the procedure for a typical precipitation gravimetric method. Although each method has its own unique considerations, the determination of Mg2+ in water and waste- water by precipitating MgNH₄PO₄ 6H₂O and isolating Mg₂P₂O₇ provides an in- structive example of a typical procedure.
