Consider the oxides Li2O, CO2,B2O3.a. Which oxide would you expect to

1.	Consider the oxides Li2O, CO2,B2O3.a. Which oxide would you expect to be the most basic?b. Which oxide would be the most acidic?c. Give the formula of an amphoteric oxide.
Answer» a. Li₂O is the most basic oxide. b. CO₂ is the most acidic oxide. c. Formula of an amphoteric oxide : Al₂O₃. [Note : Both B₂O₃ and CO₂ are acidic oxides. But CO is more acidic oxide as compared to B₂O₃. Hence, CO₂ is most acidic oxide amongst the given.]
