Q: Corrosive chemicals usually involve what kind of reactions(s)?
- Acid-base
- Redox
- Acid-base then redox
- Acid-base and/or redox
A: Acid-base and/or redox

Q: Aqua regia is a mixture of
- HCl and H_2SO_4
- HNO_3 and H_2SO_4
- HNO_3 and HNO_2
- HNO_3 and HCl
A: HNO_3 and HCl

Q: NaOH destroys living tissue quite well since it reacts readily with
- Proteins
- Esters
- Acids
- Proteins and esters
A: Proteins and esters

Q: Acetic acid can be corrosive
- At high concentrations when inhaled
- Since it is a good dehydrating agent
- Since it causes burns when exothermically reacting with water in tissue
- All of the above
A: All of the above

Q: HV should only be used
- If there has been special training on using this chemical
- If medical treatment for HF exposures are immediately available
- If a response plan for HF exposure is in place
- All of the above
A: All of the above

Q: Which halogen is relatively safe to handle in elemental form?
- Cl_2
- Br_2
- I_2
- None of the above
A: None of the above

Q: Water-reactive, dehydrating agents
- Are often solids
- Should be flushed immediately with large amounts of water upon exposure
- Should be scraped away before flushing with water
- Since they are mostly solids, they should be scraped away before flushing with water
A: Since they are mostly solids, they should be scraped away before flushing with water

Q: Phenol is
- Used as a commercial throat spray of 1% concentration
- A solid compound that reacts quickly with skin
- Also called carbolic acid
- All of the above
A: Used as a commercial throat spray of 1% concentration
