When moisture content of silica gel in a breather gets saturated, its color changes from
Right Answer is:
Blue to Pink
SOLUTION
When the moisture content of silica gel in a breather becomes saturated, the color change from blue to pink indicates that the silica gel has absorbed moisture and is no longer effective at removing additional moisture from the air. Here’s a more detailed :
Silica Gel as a Desiccant
- Function: Silica gel is a desiccant, which means it is a substance that absorbs moisture from its surroundings. It is commonly used to control humidity and prevent moisture-related damage in various applications.
- Color Change Mechanism:
- Blue Silica Gel: This type of silica gel contains cobalt chloride, which is hygroscopic and changes color based on its moisture content. When dry, it appears blue. Upon absorbing moisture, it transitions to pink, indicating saturation.
- Indicating Functionality: The color change serves as a visual indicator for users to know when the silica gel needs to be replaced or regenerated.
