What are the best practices for safely handling waste in the lab? Select one or more:...
- Place any paper towels from the clean-up in the trash.
- Check labels or instructions before any disposal.
- Remove gloves for better manipulation of the waste containers.
- Always wear appropriate Personal Protective Equipment
Homework Answers
2nd and 4th options are correct because you have to follow disposal guidelines before disposing the laboratory waste.
The remaining options are incorrect because any untreated waste can be chemically harmful.

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
