Question

Which of the following oxides are NOT amphoteric?
(A) Na2O
(B) Sno
(C) Zno
(D) Al2O3​

Answer 1

Answer:

(C) Zno

Explanation:

Based on this definition alone, there are two which stand out - ZnO and H2O .

Zinc oxide can react with acids forming zinc salts and with bases forming zinc-containing anions.

The reactions of water with acids and bases - hydronium and hydroxide formation - are the basis of the Arrhenius acid-base theory.

Note: Most answers here point out only ZnO , but it is important to look at every option, especially if it is a more-than-one-correct type question.

Answer 2

c. ZnO
