Vedclass · Answer

(D) The acidic strength of oxides increases as we move from left to right across a period in the periodic table due to the increase in electronegativity and decrease in metallic character.$Al_2O_3$ is amphoteric.$SiO_2$ is weakly acidic.$P_2O_3$ is acidic (anhydride of $H_3PO_3$).$SO_2$ is more acidic (anhydride of $H_2SO_3$).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 acidic strength is:
