What volume of 3 molar $H N O_{3}$ is needed to oxides 8 g of $F e^{2 +}$ to $F e^{3 +}$ ? $H N O_{3}$ gets converted to NO

Options:

Answer:

Solution:

$H {\overset{+ 5}{N O}}_{3} \to \overset{+ 2}{N O}$
n-factor = 5 – 2 = 3
Eq. weight of $H N O_{3} = M / 3$
$milli eq . of {HNO}_{3} = milli eq . of {Fe}^{2+}$
or $3 \times 3 \times V = \frac{8}{56} \times 1000$
So $V = 15.87 mL$
$≅ 16 mL$
