| Analysis of organic reagent is determined for inorganic elements in the separation and analysis of precipitant for enrichment, extraction agent, chelating agent and indicator for organic compounds, and not to refer to the general solvent, organic acid and organic alkali. These organic reagents must have good sensitivity and selectivity. With the development of analytical chemistry and the chemical industry, will be developed this kind of reagent sensitivity and better selectivity, such as since 1967 for some metal (such as alkali metal, alkaline earth metal) crown ether compounds and ammonium ion complexing is such. | |||||||
| Normal solution for a liter of water solution in a solution containing one gram equivalent solute, refers to the concentration of 1N solution. The indicator indicator (Indicator) is affected by the existence of certain substances to change their color material. Mainly used for indicating the end point drop in volumetric analysis. In general can be divided into acid the indicator, redox indicator, indicator indicator. In addition to adsorption analysis, can also be used to test the gas or solution of some harmful toxic substances. | |||||||
