Some Basic Concepts Of Chemistry Question 257

Question: On electrical decomposition of 150 ml dry and pure $O_{2}$ , 10% of $O_{2}$ gets changed to O, then the volume of gaseous mixture after reaction and volume of remaining gas left after passing in turpentine oil will be

Options:

A) 145 ml

B) 149 ml

C) 128 ml

D) 125 ml

Show Answer

Answer:

Correct Answer: A

Solution:

$∵$ 3ml (O) $\to$ 1ml $O_{3}$

30ml (O) $\to$ 10ml $O_{3}$

$x = \frac{150 \times 10}{100} = 15 m l$

V of $O_{2} +$ V of $O_{3} = 135 + 10 = 145 m l$

Turpentine oil absorb ozone.
