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) ${\HCl} \gas$	$\; {\NaCl}+ \; {\H}_2 {\SO}_4$	A ..........	cons. ${\H}_2 {\SO}_4$	B............
(ii) ${\NH}_3$ gas	C ............	${\Mg}( {\OH})_2 \;\;\; {\NH}_3$	D .............	E ............

Solution:

(i)

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

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

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

{\D}\;= {\CaO}

{\E}\;=\;\text " Downward displacement of Air. "\;
