Chapter 8: Sampling, Standardization, and Calibration

Chapter 8: sampling , Standardization, and Calibration A chemical analysis uses only a small fraction of the available sample, the process of sampling is a very important operation. Knowing how much sample to collect and how to further subdivide the collected sample to obtain a laboratory sample is vital in the analytical process. Statistical methods are used to aid in the selection of a representative sample. The analytical sample must be processed in a dependable manner that maintains sample integrity without losing sample or introducing contaminants.

12A-1 Properties of Precipitates and Precipitating Reagents A gravimetric precipitating agent should react specifically or at least selectively with the analyte and give precipitates that is: 1. Enough particle size for retaining on filter paper 2. High purity (free of contaminants) 3. Low solubility that no significant loss of the analyte occurs during filtration

The pH of each buffer can be calculated from the analytical concentrations of the conjugate base or acid and the concentrations of the weak acid or base that remains. 3. At the equivalence point, the solution contains only the conjugate of the weak acid or
