Question

Give an activity to show that generally metallic oxides are basic in nature.​

Answer 1

Answer:

When metallic oxides react with water they form metallic hydroxides which are basic in nature. To show that these are basic in nature,we should conduct a litmus paper test. In this experiment,we will observe that red litmus turns blue on coming in contact with them. This shows that metallic oxides are basic in nature

Answer 2

Answer:

react CuO with HCl it will give Copper chloride and water which is same as a neutralization reaction and give bluish green colour

hence metal oxides are basic
