Cobalt chloride Paper
Key Properties:
-
Chemical Composition: The paper is impregnated with cobalt chloride (CoCl₂), which is a blue compound in its anhydrous (dry) form.
-
Color Change: Cobalt chloride paper exhibits a color change based on the moisture content:
-
Blue when dry (anhydrous).
-
Pink when it absorbs moisture (hydrated form).
-
-
Sensitivity: The color change is sensitive to humidity and can detect low levels of moisture in the air or on surfaces.
Uses:
-
Humidity Detection: Commonly used to test for moisture in air or on surfaces in laboratories or storage conditions.
-
Desiccant Testing: It can be used to monitor the effectiveness of desiccants or drying agents, indicating whether they have absorbed moisture.
-
Demonstrations: Used in demonstrations to illustrate the concept of hydration and dehydration of chemical compounds.
