Equilibrium Topic Test Ionic Equilibrium Question 34
Question: The correct order of acidic strength is:
Options:
A) $ Cl_2O_7>SO_2>P_4O_{10} $
B) $ CO_2>N_2O_5>SO_3 $
C) $ Na_2O>MgO>Al_2O_3 $
D) $ K_2O>CaO>MgO $
Answer:
Correct Answer: A
Solution:
[a] As non-metallic character of element attached to oxygen atom increases, the difference between the electronegativity values of element and oxygen decreases and the acid character of oxides increases and vice-versa.
