1.	Which of the following is not an amphoteric oxide?A. `PbO_(2)`B. `PbO`C. `BeO`D. `BaO`
Answer» Correct Answer - 4 `BaO` is a basic oxide ,Basic oxides either dissolve in water to form alkalies or combine with acids to from salts and water or combine with acidic ocide to form salts. `BaO+2HCl-.BaCl_(2)+H_(2)O` The rest of the oxides are amphoteric oxides are `PbO + H_(2)SO_(4) rarr PbSO_(4)+H_(2)O` `PbO +2NaOH rarr Na_(2)PbO_(2)+H_(2)O` Other examples of amphoteric oxides are `ZnO,Al_(2)O_(3),Sb_(2)O_(3),Cr_(2)O_(3)` `ZnO+2HClrarrZnCl_(2)+H_(2)O` `ZnO+2NaOHrarrNa_(2)ZnO_(2)+H_(2)O` `Cr_(2)O_(3)+3H_(2)SO_(4)rarrCr_(2)(SO_(4))_(3)+3H_(2)O` `Cr_(2)O_(3)+2NaOH rarr Na_(2)Cr_(2)O_(4)+H_(2)O`
