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:

$ \because $ 3ml (O) $ \to $ 1ml $ O _3 $

30ml (O) $ \to $ 10ml $ O _3 $

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

V of $ O _2+ $ V of $ O _3=135+10=145ml $

Turpentine oil absorb ozone.
