Solution

The correct option is A P-2, Q-1, R-3, S-4
i) $H C l + N a O H ⟶ N a C l (P) + H_{2} O$
Here limiting reagent is $H C l$ .
$Moles of (P) i.e. N a C l formed = 20 m l \times 1 M = 20 m m o l$
$Molarity = \frac{m m o l}{Total vol.} = \frac{20}{50} = \frac{2}{5} M$

ii) $N a_{2} C O_{3} (Q) + 2 H C l ⟶ 2 N a C l (R) + H_{2} O$
$Moles of (Q) i.e. N a_{2} C O_{3} present = 20 m l \times 1 M = 20 m m o l$
$Moles of H C l present = 30 m l \times 1 M = 30 m m o l$
Here $H C l$ is limiting reagent.
$Moles of (R) i.e. N a C l formed = 30 m m o l$
$Molarity = \frac{m m o l}{Total vol.} = \frac{30}{50} = \frac{3}{5} M$

$Moles of (Q) unreacted = 5 m m o l$
$Molarity of Q = \frac{5}{50} = \frac{1}{10} M$
$Normality of Q = \frac{2}{10} = \frac{1}{5} N$

iii) $N a H C O_{3} (S) + H C l ⟶ N a C l + H_{2} O + C O_{2}$
$Molarity of S = 1 M$
