Vedclass · Answer

(A) The acidic character of oxides increases as we move from left to right across a period in the periodic table due to an increase in non-metallic character and electronegativity of the central atom.$Al_2O_3$ is amphoteric,$SiO_2$ is weakly acidic,$P_2O_3$ is acidic,and $SO_2$ is strongly acidic.Therefore,the correct order of acidic strength is $Al_2O_3 < SiO_2 < P_2O_3 < SO_2$.

Among $Al_2O_3$,$SiO_2$,$P_2O_3$ and $SO_2$,the correct order of acid strength is
