Silica Gel Self Indicating Blue 6-20 Mesh is a moisture-absorbing bead or granule that changes color from blue to pink when it reaches its maximum adsorption capacity. It contains cobalt chloride, which allows for this color change, indicating when the gel needs reactivation through heat.

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; …
Potassium Hydrogen Phthalate Extrapure AR, 99.9% is slightly acidic, and it is often used as a primary standard for acid–base titrations because it is solid and air-stable, making it easy to weigh accurately.
Sodium Carbonate, Anhydrous is a water insoluble Sodium source that can easily be converted to other Sodium compounds, such as the oxide by heating (calcination). Carbonate compounds also give off carbon dioxide when treated with dilute acids. Sodium Carbonate is generally immediately available in most volumes.
It is used in the manufacture of detergents, soaps, and paper. Also used in the manufacture of water glass (sodium silicate), borax, sodium phosphate, and many other sodium compounds.
