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

Chapter 11 Solving Equilibrium Problems for Complex Systems

Aqueous solutions often contain species that interact with one another and water to yield two or more simultaneous equilibria. Ex., for a sparingly soluble salt in water, there are three equilibria. + BaSo4(s) ⇔ Ba 2 + SO. 4-2 SO + O 4-2 H 3 + ⇔HSO. 4 - +H 2. O-2H. 2. O +⇔ H. 3. O + OH

Chapter 12: Gravimetric Methods of Analysis

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

equivalence point), the solution consists of a series of buffers. 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
