Challenge Problems
Push your limits with challenges.
Question 1
An environmental lab measures a water sample with an original concentration of a harmful chemical. After processing, the lab finds only 50 mg/L instead of the reported 100 mg/L. Calculate the recovery efficiency and discuss the implications.
💡 Hint: Repeat the recovery efficiency calculation!
Question 2
A lab uses two different types of containers for storage: glass and plastic. Explain the potential impacts of each on recovery efficiency concerning adsorption and present a comparison-based scenario.
💡 Hint: Think about how different materials interact with chemicals!
