Step 1
C. NH3
Answer
Concentrated H2SO4 is an effective dehydrating agent because it reacts with water to form dilute sulfuric acid. However, it is not suitable for ammonia (NH3) because ammonia is a gas that can react with H2SO4 to produce ammonium sulfate. This interaction makes it unsuitable for dehydration purposes. Therefore, the correct answer is C. NH3.
