Ideal Gas Equation

Reaction, 2B...

Question

Reaction,
$2 B r^{-} (a q) + C l_{2} (a q) \to 2 C l^{-} (a q) + B r_{2} (a q)$
is used for commercial preparation of bromine from its salts. Suppose we have 50 mL of a 0.06 M solution of NaBr. What volume of a 0.05 M solution of $C l_{2}$ is needed to react completely with the $B r^{-} ?$

Open in App

Solution

$2 B r^{-} (a q) + C l_{2} (a q) \to 2 C l^{-} (a q) + B r_{2} (a q)$
$\frac{M_{1} V_{1} (B r^{-})}{n_{1}} = \frac{M_{2} V_{2} (C l_{2})}{n_{2}}$
where, $n_{1}$ and $n_{2}$ are corresponding number of moles.
$\frac{0.06 \times 50}{2} = \frac{0.05 \times V_{2}}{1}$
$∴ V_{2} = 30 m L$
