Question

What are the types of oxides according to the nature

Answer 1

Answer:

According to the Nature oxides are classified into two categories-

Simple oxide-

Oxides having metals in only one oxidation state .

Example- $MgO , Al_{2}O_{3} , Na_{2} O, K_{2}O \ etc.$

Simple oxides are classified into four sub-categories.

• Acidic oxides- They are formed by reaction of non metals with oxygen.

Example- $S_{8} + 8O_{2}$ → $8SO_{2}$

• Basic oxides- Metals react with $O_{2}$ and forms basic oxides.

Example- $2Ca + O_{2}$ → 2CaO

• Amphoteric oxides- Some elements forms oxides by reaction with $O_{2}$ which is amphoteric in nature.

Example- $H_{2} O + NH_{3}$ → $NH_{4} OH$

• Neutral oxide- Oxides which do not change pH of water when dissolved in it and neither behave as acid nor as base.

Example- $CO,NO,N_{2} O$

Mixed oxide-

Oxides having metals in only one oxidation state.

Example- $FeO, Fe_{2} O_{3}$
