What color is CaH2?
Calcium hydride is an inorganic substance with a chemical formula of CaH2 and a molecular weight of 42.10. Grayish-white crystals or lumps, easily deliquescent, used as reducing agents, desiccants, chemical analysis reagents, etc.; it is also a colorless orthorhombic crystal; industrial products are gray, orthorhombic or powder.
What substances does CaH2 react with?
It does not react with dry air, nitrogen, or chlorine at room temperature, but can react with the above gases at high temperatures to generate calcium oxide, calcium nitride, and calcium chloride, respectively.

What happens when CaH2 reacts with water?
Calcium hydride (CaH2) reacts violently with water, releasing hydrogen gas. The activation energy of the hydrolysis reaction of CaH2 in ethanol solution (Ea = 20.03 kJ/mol) is less than other reactions.

What bonding occurs in calcium hydride?
Then calcium loses electrons, and these two electrons are accepted by hydrogen. Then the compound calcium hydride is formed through the donation of calcium electrons, and these electrons are accepted by two hydrogen atoms. Therefore, calcium hydride is an ionic compound or ionic hydride.

Is calcium hydride dangerous?
Inhaling calcium hydride can irritate the lungs and cause coughing or shortness of breath. Higher exposures can cause fluid to accumulate in the lungs (pulmonary edema), which is a medical emergency accompanied by severe shortness of breath. Calcium hydride is a flammable and reactive chemical with fire and explosion hazards.

How do you neutralize calcium hydride?
An easy way to neutralize calcium hydride is to slowly add it to a large amount of water in a well-ventilated area. A slower but safer method is to expose calcium hydride to water vapor. Instead of water, long-chain alcohols can also be used to neutralize the compound.

Does calcium respond to oxygen?
At room temperature, calcium reacts with oxygen to form a thin layer of CaO, protecting the metal from further oxidation. Calcium can be ignited and will react with oxygen and nitrogen to form calcium oxide (CaO) and calcium nitride (Ca3N2) when burned.

Method for detecting water ingress in lubricating oil
The use of a calcium hydride pressure detection device is also a simple operation method for on-site detection. The principle is that the reaction of water and calcium hydride will release hydrogen gas, which will cause the pressure in the closed container to change. The change in pressure can calculate how much water has reacted with calcium hydride. This method is less costly.
