Question

1. Which of the above oxides will react with hydrochloric acid but not with aqueous sodium hydroxide?

Answer 1

Answer:where are the oxides?

Explanation: hope this helps

Answer 2

The oxides with hydrochloric acid but not with aqueous sodium hydroxide are the ones that are basic in nature.

• Metallic oxides, like $K_2O, Na_2O and MgO$ are basic in nature, so they react with HCl performing a neutralization reaction to form water and salt.
• Whereas, metallic $SO_2, SO_2, and CO_2$oxides like are acidic in nature and so they react with bases like NaOH (aq).
• There are some amphoteric oxides like the oxides of Zn, that react with both acids and bases.
