Question 1 1 pts What is the major hazard associated with the use of phosphoric acid? Explosive Flammable Cryogenic CorrosiveIsn't phosphoric acid corrosive, flammable, and explosive? I'm confused on how we are supposed to know which one is "the major hazard". Were performing a gas chromatography experiment and so heat will be involved, maybe then the answer would be explosive?

Answer #1

Phosphoric acid is not flammable or explosive on itself.

Cryogenic means when gaseous substance is stored under liquid conditions by cooling down to very low temperature.

Hence phosphoric acid is not cryogenic as well.

However, phosphoric acid is dehydrating agent and it is Corrosive in nature.

Thus your answer is option 4) Corrosive.
