After drying, filter papers and crucibles should be stored in a ______ to prevent moisture uptake from the atmosphere.

• A. Dessicator
• B. Desiccator
• C. Drying cabinet
• D. Seal bag

Answer: (A)

After drying, you want to keep the items from reabsorbing moisture from the air. A desiccator is a sealed chamber that holds a desiccant (like silica gel or calcium chloride). When you place the dried filter papers and crucibles inside, the desiccant actively pulls water vapor out of the air inside the chamber, so the contents stay dry until you’re ready to weigh or use them. This helps prevent moisture uptake that could alter mass or other properties. Note that the correct term is desiccator (not a common spelling variation). Other options like a drying cabinet aren’t intended for long-term storage of already-dried items, and a seal bag may not maintain as low humidity as effectively.
