This is a very general question which has a wide variety of answers.
However, Calcium Chloride (CaCl2) is often (but not exclusively) used to dehumidify air. Calcium Chloride is very hygroscopic, meaning that it will absorb water readily from the surrounding air.
You will often see products using CaCl2 crystals designed so that Calcium Chloride will absorb the water from moist air in conditions which it may not be favorable to have very humid air.

For what experiments?
It has a variety of uses such as in dust binding on roads, oil drilling and applications in the food-processing industry. Since its most striking property is its ability to draw moisture from the air and so dissolve itself (deliquescence), it is often used as an air dryer (drying agent) and as a de-icing, as well as antifreeze.
