Environmental Chemistry Question 28
Question: $ SO_2 $ can be removed by using the following
$ SO_2+2H_2S\to 2H_2O+3S $ $ SO_2+Na_2SO_3+H_2O\to 2NaHSO_3 $ This is called
Options:
A) synergistic process
B) non-regenerative process
C) desulphonation process
D) regenerative process
Show Answer
Answer:
Correct Answer: D
Solution:
