Question

Quizplus · Accepted Answer

Both technicians are correct. The powdery residue on air bags is typically a combination of sodium carbonate and corn starch. Sodium carbonate is used to neutralize the acids that are produced when the air bag is deployed, and corn starch is added to prevent the sodium carbonate from clumping together.
