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.

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.
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 bicarbonate (KHCO3) is an inorganic compound that appears as a white solid. It is commonly used as an antacid, leavening agent in baking, and a buffering agent in various applications. It can also serve as a potassium supplement and is recognized for its role in regulating pH levels in food and agriculture.
Buffer solution, pH 4.0 ± 0.02 is used to establish and maintain an ion activity within narrow range. It is most commonly used to establish hydrogen-ion activity for the calibration of pH meters, in analytical procedures. It is also used to maintain stability of various dosage forms.
Thymol blue is used as a pH indicator. It is insoluble in water but soluble in alcohol and dilute alkali solutions. It transit from red to yellow at pH 1.2–2.8 and from yellow to blue at pH 8.0–9.6. It is usually a component of Universal indicator.
