Question

How will you prove that metallic oxides are basic in nature?

Answer 1

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

Answer 2

metallic oxide is basic in nature just take one example

Na2O + H2O ---------------> NaOh


so metal oxide reacts with water and form metal hydroxide so it is basic in nature
