a solid compound which contains water molecules in its crystalline structure
Compounds that have an affinity for water are known as hygroscopic. If the affinity is strong enough to attract water until the compound goes into solution, they are called deliquescent.
Acetone is not known as hygroscopic.
Anhydrous calcium chloride is a hygroscopic compound, meaning it readily absorbs moisture from the atmosphere. When exposed to air for an extended period, it will pull in water vapor and dissolve, forming a solution of calcium chloride and water. This process is exothermic, generating heat as it occurs.
To calculate the percent water in a hydrate, you first determine the mass of water in the hydrate by subtracting the mass of the anhydrous compound from the mass of the hydrate. Then, divide the mass of water by the total mass of the hydrate and multiply by 100 to get the percentage.
Hygroscopic substances include cellulose fiber such as ethanol, methanol and diesel fuel. As hydrogen bonding causes pure ethanol to readily absorbs water from the air, ethanol is considered to be hygroscopic.
Barium chloride BaCl2 is quite hygroscopic and thus might exist as di-hydrate: BaCl2.2H2O Extra: BaCl does NOT exsist.
Non-Hygroscopic
Compounds that have an affinity for water are known as hygroscopic. If the affinity is strong enough to attract water until the compound goes into solution, they are called deliquescent.
The hair of the tail of horse is hygroscopic material.
Polyol Ester is also hygroscopic
Hygroscopic substances are used to absorb humidity.
Potassium hydroxide is hygroscopic and deliquescent.
Yes its a hydrate = Crystalline hydrate
As far as I know, the PVC is not hygroscopic, it doesn't absorb the moisture. There are several types of PVC though, so there could be some hygroscopic PVC resin, but I haven't encountered it yet. Normally it is dried by hot air driers, which are not suitable for hygroscopic materials, therefore I assume PVC is not hygroscopic...
No.
Acetone is not known as hygroscopic.
No, it is not a hydrate.
