Weigh boats are used when weighing substances. After weighing, what should you do with them?

• A. Reuse weigh boats for multiple trials
• B. Place weigh boats on the balance
• C. Use weigh boats and then throw weigh boats in the trash
• D. Throw weigh boats in the trash

Answer: (C)

Weigh boats are designed for single use to prevent cross-contamination and keep measurements accurate. After weighing, residues and contamination remain on the boat, so reusing it could transfer material to a new sample and skew results. Placing the used boat back on the balance would contaminate the balance and future measurements. The right action is to discard the used weigh boat after weighing. In many labs that means throwing it in the trash, though hazardous materials would follow your lab’s specific waste disposal rules. This practice keeps future trials clean and trustworthy.
