From: JEE Main 2020 (Online) 7th January Evening Slot
Question
The ammonia (NH3) released on quantitative reaction of 0.6 g urea (NH2CONH2) with sodium hydroxide (NaOH) can be neutralized by :
Choose an option
Show full solutionCorrect option: B
Correct answer
B100 ml of 0.2 N HCl
Step-by-step explanation
NH2CONH2 NH3
Using Principle of Atom Conservation
2 moles of urea = 1 moles of NH3
2
moles of NH3 = 0.02
Also moles of NH3 = moles of HCl, because they react in 1 : 1 ratio.
100 ml of 0.2 N HCl = = 0.02 mole of HCl
So option (B) is correct.
