Marks: +1, -0

Certain blank spaces are left in the following table and these are labelled as A, B, C, D and E. Identify each of them.

Lab. Preparation of	Reactants used	Products formed	Drying agent	Method of Collection
(i) $\mathrm{HCl} \text{ gas}$	$\; \mathrm{NaCl} + \; \mathrm{H}_2\mathrm{SO}_4$	A ..........	cons. $\mathrm{H}_2\mathrm{SO}_4$	B............
(ii) $\mathrm{NH}_3$ gas	C ............	$\mathrm{Mg}(\mathrm{OH})_2 \; \; \; \mathrm{NH}_3$	D .............	E ............

Solution:

(i)

A \; = \mathrm{NaHSO}_4 + \mathrm{HCl}

B = \text{Upward} \; \text{displacement of Air}

\text{(ii)} C = \mathrm{Mg}_3\mathrm{N}_2 + \mathrm{H}_2\mathrm{O}

D = \mathrm{CaO}

E = \text{Downward displacement of Air.}
