Question

difference between deliquescent substance and hygroscopic substances

Answer 1

Hi user

Difference between hygroscopic and deliquescent is in the extent to which each material can absorb moisture. This is because both of these terms are very much related to each other, and they refer to the property of absorbing and the retention of moisture from the air. However, they differ in the extent of absorption of moisture where hygroscopic materials absorb moisture, but not to the extent the original substance dissolves in it, which is the case with deliquescence. Therefore, deliquescence can be regarded as an extreme condition of hygroscopic activity.

Answer 2

The water soluble substance which absorb moisture from the air and then dissolve on the absorbed moisture to change into liquid taste are called deliquescent substances whereas the substances which absorb moisture from air but do not change their state are called hygroscopic substances.
