Question
The equivalent volume of a gaseous substance is 5.6 L at 0o C and 1 atm. The substance may be
Options
A.CH4 gas in combustion.
B.O3 gas as oxidizing agent.
C.H2S gas as reducing agent.
D.CO2 formed from carbon.
Solution
Equivalent volume is the volume occupied by 1g-equivalent of the gas.
(a) 1g-equivalent of CH4 = $\frac{1}{8}\text{ mole = }\frac{1}{8} \times 22.4\text{ L = 2.8 L}$
(b) 1g-equivalent of $O_{3} = \frac{1}{2}\text{ mole = 11.2 L}$
(c) 1g-equivalent of $H_{2}S = \frac{1}{2}\text{ mole = 11.2 L}$
d) 1g-equivalent of $CO_{2} = \frac{1}{4}\text{ mole = 5.6 L}$
