Qualitative Analysis of Aqueous Solutions
control abilities make it an effective antimicrobial agent. In other cases, it is possible to bombard a nonradioactive sample with a particle or with radiation in order to transform temporarily all or part of the sample into a radioactive material that can be assayed. An electron microprobe functions in much the same manner. The analyte must be capable of either accepting one or more electrons (known as reduction ) from the electrode or donating one or more electrons ( oxidation ) to the electrode. The fluctuating field induces an electric dipole (separation of charges equal in size but opposite in sign) within the scattering particles that oscillates at the same frequency as the incident radiation. What is the test for chromium(III) ions? This method is called isotopic dilution analysis. Electrogravimetry is a gravimetric technique similar to the classical gravimetric methods that were described above, in which the solid that is weighed is deposited on one of the electrodes. Environmental agencies monitor levels of oxygen and pollutants in rives and lakes. What is the test for lead(II) ions? Aqueous means a solution in water.
The analytical method that measures the diffraction patterns for the purpose of determining structure is termed X-ray diffraction analysis.

What is the test for zinc ions? Typically the potential is initially adjusted to a value at which no electrochemical reaction occurs at the indicator electrode. Computerized comparisons of analyte mass spectra with mass spectra of known materials is commonly used to identify an analyte. The internal reference electrode and reference solution are separated from the analyte solution by a membrane that is chosen to respond to the analyte. Microwave absorptiometry In a manner that is similar to that described for nuclear magnetic resonance spectrometry, electron spin resonance spectrometry is used to study spinning electrons. The shape of a voltammogram depends on the type of indicator electrode and the potential ramp that are used.
