What information in the msds would be most important to know at the end of an experiment? 1. boiling point 2. the flammability 3. the disposal procedure. 4. the reactivity

The answer is: 3. the disposal procedure.

Since we are talking about the end of an experiment, the most important information will be the disposal procedure.

Not all materials can be disposed as common materials, there are a lot of chemical substances that should be properly disposed since it can affect the ambient, animals, and even people.

If we were talking about of the start of the experiment, the most important information to know (at least the first one) is the flammability of the substance in order to know how to handle the substance and how could interact in presence of others substances.

Have a nice day!
