Equilibrium Question 240
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 acid and they give electron pair to $ H_3{O^{+}} $ ion. $ H_3{O^{+}} $ is a Lewis base. Which accept the electron pair from $ NH_3 $ .
