Which of the following oxides reacts with both hydrochloric acid and sodium hydroxide solution to form a salt and water?

Zinc oxide ( $\text{ZnO}$ )Cevap
B
Calcium oxide ( $\text{CaO}$ )
C
Carbon(IV) oxide ( $\text{CO}_2$ )
D
Carbon(II) oxide ( $\text{CO}$ )

Cevap

Zinc oxide (

\text{ZnO}

)

Zinc oxide (

\text{ZnO}

) is amphoteric, allowing it to act as a base in the presence of an acid and as an acid in the presence of a base, forming salt and water in both cases.

Adım Adım Çözüm

Identify the property of reacting with both acids and bases.

Oxides that react with both acids and alkalis to form salt and water are classified as amphoteric oxides.

Amphoteric oxides exhibit both basic and acidic chemical behavior.

Select the amphoteric oxide from the options.

Zinc oxide (

\text{ZnO}

) reacts with

\text{HCl}

to form

\text{ZnCl}_2

and

\text{H}_2\text{O}

, and with

\text{NaOH}

to form

\text{Na}_2\text{ZnO}_2

and

\text{H}_2\text{O}

Zinc, aluminium, and lead oxides are key examples of amphoteric oxides.
