These are compounds that absorb or adsorb water vapour from air. Some may absorb so much water they actually dissolve in the water they have absorbed and one is left with a solution. Instant coffee granules will do this, left for a few hours, they turn from powder to a gooey puddle. The hygroscopic properties of silica gel are commonly used to keep some foods, drugs and electronic equipment dry by including little sachets of the silica in the packaging of these products. Often, a small amount of cobalt II chloride is added to the silica pellets giving them the added ability to change colour depending upon how much water they have absorbed. When completely dry, the pellets are a strong blue colour and when they have absorbed water they turn a pale pink. Pale pink silica pellets may be returned to blue ones by heating in an oven, thus rendering them capable of re-use.
What else can I help you with?
Compounds that hold water?
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.
Is acetone hygroscopic?
Acetone is not known as hygroscopic.
What is ionic compounds that absorb water into their solid structure form?
Ionic compounds that absorb water into their solid structure form are known as hygroscopic compounds. These compounds have a strong affinity for water molecules and can readily absorb moisture from the surrounding environment. Examples include salts like calcium chloride and sodium hydroxide.
Is ethanol considered to be hygroscopic?
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.
Is potassium gold cyanide hygroscopic?
In crystalline form it's non-hygroscopic, or has only slight hygroscopicity. In powder form it is, yes.
What is a family of compounds that can hold water?
hygroscopic compounds, polyacrylamide, sodium acrylate, etc.
What is the definition of standardization of hygroscopic compound?
Standardization of a hygroscopic compound involves establishing a consistent and accurate method for measuring its water content. This can involve using standardized procedures, equipment, and calculations to ensure reliable results. Standardization is important for ensuring consistency in research, quality control, and manufacturing processes involving hygroscopic compounds.

What is a compound that gains so much water that can be used to dry other substances?
These compounds are hygroscopic and are called dessicants.
What is the opposite of Hygroscopic?
Non-Hygroscopic
Where can you get hygroscopic material?
The hair of the tail of horse is hygroscopic material.
WHAT refrigerant oil is hygroscopic?
Polyol Ester is also hygroscopic
Hygroscopic substances and their use?
Hygroscopic substances are used to absorb humidity.
Is potassium hydroxide hygroscopic efflorescent or deliquescent?
Potassium hydroxide is hygroscopic and deliquescent.
When Compounds have an affinity for water are said to be?
Hydrophilic. These compounds have a tendency to interact and dissolve in water due to their polarity or ability to form hydrogen bonds with water molecules. Examples of hydrophilic molecules include sugars, salts, and some proteins.
Is polyvinyl chloride PVC hygroscopic?
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...
Are diamonds hygroscopic?
No.
