Question

Heating ammonium chloride will produce

i. A gas turns moist red litmus blue

ii. A gas turns moist blue litmus red

iii. Gases are highly soluble in water

• A. Only (i)
• B. (i) and (ii)
• C. (i) , (ii) and (iii)
• D. (ii) and (iii)

Answer 1

The correct option is C

(i) , (ii) and (iii)

1. The heating of Ammonium chloride will produce Ammonia and Hydrochloric acid after decomposition.
2. $\underset{(Ammoniumchloride)}{\underbrace{N{H}_{4}Cl\left(aq\right)}}\stackrel{Heating}{\to }\underset{\left(Ammoniagas\right)}{\underbrace{N{H}_3\left(g\right)}}+\underset{(Hydrogenchloridegas)}{\underbrace{HCl\left(g\right)}}$
3. Here Ammonia produced is basic, so it will turn red litmus blue, hence statement (i) is correct.
4. Hydrogen Chloride produced is acidic, so it will turn blue litmus red., hence statement (ii) is correct.
5. And Both Ammonia $\left(N{H}_3\right)$ and Hydrogen chloride $\left(HCl\right)$ are highly water-soluble so statement (iii) is also correct.

Hence option (C) is the correct option.
