Solution


Q.

Metal oxides are:
1 acidic  
2 basic  
3 neutral  
4 none of the above  

Ans.

(2)

Oxides of metals are basic in nature because they react with water to form metal hydroxides which are alkaline in nature. These metal hydroxides when dissolved in water release OH- ions in solution which will turn red litmus solution to blue. Therefore, non-metallic oxides are acidic in nature.
