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; …
Nickel (II) Sulphate Heptahydrate-It is used in electroplating and as a chemical intermediate to produce other types of nickel compounds. Nickel Sulfate is a by-product of copper refining and it naturally occurs as a rare mineral which is retgersite.
Ferrous Sulfate is a greenish, yellow-brown or white, odorless, crystalline (sand-like) powder. It is used in water treatment and in making other Iron compounds, and as a fertilizer and food additive.
Ferrous metals are hard, heavy, have high density, fragile, not malleable, ductile, magnetic, and rust. Non-ferrous metals are light, malleable, not magnetic, and more expensive. There are different ferrous metals, and each one has its uses. For example, steel is used in buildings, skyscrapers, and structures.
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.
