underset0.1 M AgNO 3 longrightarrow Ag ++ underset0.1 m arrow text volume = N 3- N 1 M1 V1=M2 V2 Equal volume 0.1 × V=M2[V1+V2] [N1=V2=V] 0.1 × V=M2[V+V] M 2=(0.1 V /2 V )=0.05

Q. Equal volumes of 0.1 M $A g N O_{3}$ and 0.2 M NaCl are mixed. The concentration of $N O_{3}^{-}$ ions in the mixture will be

0.1 M

0.05 M

0.2 M

0.15 M

$0.1 M A g N O_{3} ⟶ A g^{+} + 0.1 m \to volume = N_{3}^{-} N_{1}$
$M_{1} V_{1} = M_{2} V_{2}$ Equal volume
$0.1 \times V = M_{2} [V_{1} + V_{2}] [N_{1} = V_{2} = V]$
$0.1 \times V = M_{2} [V + V]$
$M_{2} = \frac{0.1 V}{2 V} = 0.05$
