| 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. | |||||||
| Chemical reagents are often spoiled by improper storage in storage. Some easy moisture absorption and deliquescence or hydrolysis reagent; some easily with oxygen in the air, carbon dioxide or other gases in the diffusion reaction, and some reagents affected by light and temperature will deteriorate. Therefore, according to the different properties of reagents, appropriate measures should be taken to properly preserve them. | |||||||
