Question

what should you do after finishing work with a reagent bottle? select one or more: return the bottle to its proper storage location. place the bottle in the solid waste container. leave the bottle open in case someone else needs it. close the bottle.

Explanation:

• Returning the bottle to its proper storage location is correct as it follows lab organization and safety protocols for reagent storage.
• Placing the bottle in solid waste is wrong because reagent bottles (unless empty and properly cleaned as per waste disposal rules, which isn't indicated here) are not solid waste.
• Leaving the bottle open is incorrect as it can lead to contamination, evaporation, or reaction with air, compromising the reagent and lab safety.
• Closing the bottle is correct to prevent contamination, evaporation, or accidental spills.

Answer:

A. Return the bottle to its proper storage location.
D. Close the bottle.
