Question

Most of the oxides of metals when react with acids form

Answer 1

Explanation:

Metal oxides react with acid to form salt and water because most of the metal oxides are basic or amphoteric in nature.

Answer 2

Most of the oxides of metals when react with acids form water and salt.

Explanation:

• Metals are electropositive elements.
• Metal oxides are basic in nature.
• These oxides also show amphoteric  nature.
• Metal oxides react with acids to form salt and water.
• This reaction is similar to that of neutralization reaction.

• An example for the reaction of metal oxide with acid is,$\[PbO+2HCl\to PbC{{l}_{2}}+{{H}_{2}}O\]$

• Zinc oxide is an example for amphoteric oxide which means this oxide shows both acidic and basic characters.
