Chapter 5: Errors in Chemical Analyses

Chapter 5: Errors in Chemical Analyses Source: of Analytical Chemistry, Holler, Measurements invariably involve Errors and uncertainties. it is impossible to perform a Chemical analysis that is totally free of Errors or uncertainties We can only hope to minimize Errors and estimate their size with acceptable accuracy Errors are caused by faulty calibrations or standardizations or by random variations and uncertainties in results. Frequent calibrations, standardizations, and Analyses of known samples can sometimes be used to lessen all but the random Errors and uncertainties. The term error has two slightly different meanings.

interfere with the measurement process. Errors inherent in a method are often difficult to detect and hence, these errors are usually the most difficult to identify and correct.

Chapter 8: Sampling, Standardization, and Calibration

web.iyte.edu.tr

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

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

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
