Detailed Product Description: | Jing Chi Bose equipment operators, agents] [acid copper light, reagents provided by Jing Chi Bose equipment operators. We are Dongguan Changan Jing Chi Bose equipment operators (www.jingchb.com) at: Dongguan, Guangdong specialized in: Bose equipment, plastic products, laboratory supplies, hardware, labor, and office supplies. Product Code: 2171536616 Product Name: indicator category Specifications: AR25G Remarks: All kinds of indicators Category :( a) chemical reagent chemicals in a class. Under certain conditions of the medium, which can change the color of the indicator, can produce turbidity or precipitate, and the fluorescence phenomenon. It is commonly used in the pH of the test solution; titration analysis is used to indicate the titration end point; environmental testing in the test of harmful substances. Generally divided into acid-base indicator, redox indicator, metal indicator, such as adsorption indicator. To indicate the endpoint of the titration reagents. In all types of titration process, with the addition of the titrant, is the concentration of substances and titrant titration are constantly changing, such as when in the vicinity of the larger changes in the concentration of zinc ions occur light reagent capable of such ion concentration make changes in the display (such as changing the color of the reagent solution to generate precipitation, etc.) reagents called indicator. If titration Titrant or substance is colored, which itself has a function of the indicator, such as potassium permanganate. Potassium is silver-white metal cube structure, physicochemical properties and sodium are very similar. Potassium soft and light available light knife cutting acid copper reagent, new section has a silvery sheen. Potassium is a good conductor of heat and electricity, and has good permeability, potassium sodium alloy (liquid) is a nuclear reactor thermal agent. Elemental potassium also has good ductility, hardness low nickel light reagent supplier, can dissolve in mercury and liquid ammonia, dissolved in liquid ammonia to form a blue solution. Isotopes of potassium has been found a total of 28 species, including from 32 K to 55 K, which occurs in nature only 39 K, 40 K and 41 K, other isotopes are manufactured by a human. Radioactive potassium 40, is one of the important sources of natural radioactivity in rocks and soils of the background. |
