Question

Which of the following can behave as amphoteric oxide? (A)  Al2O3  (B)  Na2O  (C)  SO2  (D)  Al2O3

Tardigrade Admin · Accepted Answer

Al 2 O 3 is an amphoteric oxide. It dissolves in both acid and base. Al 2 O 3+3 H 2 SO 4 arrow Al 2( SO 4)3+3 H 2 O Al 2 O 3+2 NaOH arrow 2 NaAl 2+ H 2 O

Q. Which of the following can behave as amphoteric oxide?

$A l_{2} O_{3}$

$N a_{2} O$

$S O_{2}$

$A l_{2} O_{3}$

$A l_{2} O_{3}$ is an amphoteric oxide. It dissolves in both acid and base.
$A l_{2} O_{3} + 3 H_{2} S O_{4} \to A l_{2} (S O_{4})_{3} + 3 H_{2} O$
$A l_{2} O_{3} + 2 N a O H \to 2 N a A l_{2} + H_{2} O$

Q. Which of the following can behave as amphoteric oxide?

Al2​O3​

Na2​O

SO2​

Al2​O3​

Al2​O3​ is an amphoteric oxide. It dissolves in both acid and base. Al2​O3​+3H2​SO4​→Al2​(SO4​)3​+3H2​O Al2​O3​+2NaOH→2NaAl2​+H2​O

$A l_{2} O_{3}$

$N a_{2} O$

$S O_{2}$

$A l_{2} O_{3}$

$A l_{2} O_{3}$ is an amphoteric oxide. It dissolves in both acid and base.
$A l_{2} O_{3} + 3 H_{2} S O_{4} \to A l_{2} (S O_{4})_{3} + 3 H_{2} O$
$A l_{2} O_{3} + 2 N a O H \to 2 N a A l_{2} + H_{2} O$
