Toluene Extrapure AR is a high-quality analytical reagent used in various laboratory applications. Known for its high purity and consistent performance, it is ideal for precise chemical analysis and synthesis in research and industrial laboratories.
Sodium chloride is used as an electrolyte replenisher to help prevent heat cramps caused by too much sweating. This medicine is also used for the preparation of normal isotonic solution of sodium chloride.
Calcium chloride is an a white crystalline solid at room temperature, and it is highly soluble in water.
It has several common applications such as brine for refrigeration plants, ice and dust control on roads, and in cement.
It can be produced directly from limestone, but large amounts are also produced as a by-product of the Solvay process. Because of its hygroscopic nature, it must be kept in tightly-sealed containers.
The invention relates to a method for producing calcium chloride dihydrate, which is characterized by comprising the following steps: putting hydrochloric acid (31%) and limestone powder into a reaction vat according to the mixture ratio of 2.2:1, and stirring for reaction to generate an acid calcium chloride solution; …
Methanol Extrapure AR, 99.8%, 2.5L is a high-purity solvent ideal for analytical and research applications. With its excellent solvency and consistent quality, it is essential for a wide range of laboratory processes.
The purpose of adding sodium thiosulfate is to remove the excess iodine from the reaction mixture. This is important because iodine is a strong oxidizing agent and can cause side reactions with the organic compounds in the mixture.
