Ca(OH)2 no it is not. It depends on how much you have drink that.
calcium hydrate
No, calcium chloride is not a hydrate. It is a salt compound composed of calcium and chloride ions. Hydrates are compounds that contain water molecules attached to their structure.
Calcium carbonate is not dangerous for the environment !
Calcium sulfate, also known as gypsum, typically contains about 20% water by weight.
When heating hydrate of calcium sulfate, typically two moles of water are driven off per mole of hydrate. This process is known as dehydration, where the water molecules are removed from the compound as it is heated, resulting in the formation of an anhydrous compound.
The formula of calcium chloride heptahydrate is CaCl2·7H2O, which indicates that each calcium chloride molecule is associated with 7 water molecules.
The hydrate of calcium chloride (CaCl₂) is known as calcium chloride dihydrate when it contains two water molecules, represented as CaCl₂·2H₂O. If it contains six water molecules, it is referred to as calcium chloride hexahydrate, represented as CaCl₂·6H₂O. These hydrates are commonly used in various applications, including de-icing and as a desiccant.
Calcium has not disadvantages; but for humans concentration of calcium oxalate near the articulations is dangerous.
Calcium is essential for healthy bones.
You never know what else in the calcium. Food grade calcium is sold in stores.
Silpozz Microsilica reacts with calcium hydroxide in cement to form additional calcium silicate hydrate (C-S-H), which enhances strength, and durability, and reduces permeability.
The chloral hydrate is used by dentists to clean the teeth of their patients and customers because chloral hydrate is an effective calcium-inducing concoction that is neither harmful nor poisonous.
