Equilibrium Question 66
Question: The concentration of which ion is to be decreased, when $ NH_3 $ solution is added [RPMT 1997]
Options:
A) $ O{H^{-}} $
B) $ NH_4^{+} $
C) $ H_3{O^{+}} $
D) $ O_2^{-} $
Show Answer
Answer:
Correct Answer: C
Solution:
Because $ NH_3 $ acts as Lewis base and it donates an electron pair to $ H_3{O^{+}} $ ion. $ H_3{O^{+}} $ is a Lewis acid. Which accepts the electron pair from $ NH_3 $ .
