WebWhich pair of oxides is acidic in nature? A N 2O,BaO B CaO,SiO2 C B2O3,CaO D B2O3,SiO2 Solution The correct option is D B2O3,SiO2 B2O3 and SiO2 both are oxides of non-metal and hence are acidic in nature. CaO and BaO are oxides of metals hence, they are basic in nature. Thus, option (d) is correct. Suggest Corrections 1 Similar questions Q.
