Options:
A) $ Ca{{(OH)}_2} $
B) $ H_2SO_4 $
C) Both [a] and [b]
D) None of these
Show Answer
Answer:
Correct Answer: C
Solution:
[c] $ Ca{{(OH)}_2}+2NO_2\to Ca{{(NO_2)}_2}+H_2O $ $ H_2O+O+NO_2\xrightarrow{H_2SO_4}HNO_3 $ (Oxidation) $ Ca{{(OH)}_2}+SO_2\to CaSO_3+H_2O $ $ SO_2+H_2O+O\xrightarrow{H_2SO_4}H_2SO_4 $
